Dispositional self‐compassion and responses to mood challenge in people at risk for depressive relapse/recurrence

This paper explores the relationship between dispositional self‐compassion and cognitive emotion regulation capacities in individuals with a history of depression. Study 1 (n = 403) established that self‐compassion was associated with increased use of positive and decreased use of negative strategies, with small to medium sized correlations. Study 2 (n = 68) was an experimental study examining the association between dispositional self‐compassion, use of cognitive emotion regulation strategies, and changes in mood and self‐devaluation in participants exposed to a negative mood induction followed by mood repair (mindfulness, rumination, silence). Individuals with higher levels of dispositional self‐compassion showed greater mood recovery after mood induction, and less self‐devaluation across the experimental procedure, independent of their mood‐repair condition or habitual forms of cognitive emotion regulation. These results suggest that self‐compassion is associated with more adaptive responses to mood challenges in individuals with a history of recurrent depression.

mood, individuals with a history of depression need to apply skills and resources to respond to this mood and the negative thought content that might automatically and habitually be triggered in a more adaptive way and negative events in people with a history of depression, and the way these responses relate to individual differences in dispositional self-compassion.
Compassion has been defined as "an orientation of mind that recognizes the presence of pain, the universality of pain in human experience and the capacity to meet pain with kindness, empathy, equanimity and patience" (Feldman & Kuyken, 2011). Self-compassion refers to the ability to relate to one's own experience with the same qualities of mind and has been described as comprising three core dimensions: self-kindness versus self-judgement, common humanity versus isolation, and mindfulness versus over-identification (Neff, 2003b). The relationship between mindfulness and self-compassion is complex. Several of the key elements of self-compassion (recognizing and attending to suffering, being able to be open to and tolerate these thoughts and feelings, alongside an attitude of care) are present in definitions of mindfulness. Likewise, the ability to attend to and hold pain in awareness seen as a necessary prerequisite for self-compassion (Neff, 2003a(Neff, , 2003b. However, the important elements of common humanity and motivation to act/acting to alleviate suffering (Strauss et al., 2016) are distinct to the concept of self-compassion.
In this paper, we use the term dispositional self-compassion to refer to people's self-reported general tendency to be compassionate towards themselves.
It is suggested that when a person at risk for depressive relapse responds to negative mood with self-compassion, the subsequent prolongation or exacerbation of low mood may be diminished (Krieger, Berger, & Holtforth, 2016;Pauley & McPherson, 2010) because the negative thoughts and feelings that arise can more easily be seen for what they are, over-learned and unhelpful beliefs and attitudes.
Rather than engaging in increasingly negative, self-critical and selfdevaluative thinking, when a person is able to observe their thoughts and feelings compassionately, contextualizing them not only within their own personal life story or narrative but also within the context of broader human experience, this may reduce avoidance of negative mental content and facilitate adaptive responding, including seeing things from a new perspective, engaging in positive reappraisal and making positive behavioural change. Self-compassion is potentially important for people vulnerable to depressive relapse because it can be invoked at the times of greatest risk for depression (e.g., low mood and cognitive reactivity), bypasses self-devaluative processing (e.g., self-criticism, catastrophizing, rumination) and may enable people to step out of reactivity and utilize resilient cognitive and behavioural strategies.
There are now a number of correlational studies showing a relationship between self-compassion, well-being, and mental health (Broderick, 2005;Fredrickson, Cohn, Coffey, Pek, & Finkel, 2008;Huffziger & Kuehner, 2009;Krieger et al., 2016;. Studies show that self-compassion is consistently negatively associated with avoidance, rumination, and depressive symptom severity in depressed patients (e.g., Krieger, Altenstein, Baettig, Doerig, & Holtforth, 2013), that levels of self-compassion and self-criticism differentiate currently and previously depressed individuals from never-depressed controls (e.g., Ehret, Joorman, & Berking, 2015) and that the association between self-compassion and depressive symptoms is mediated by the ability to tolerate negative emotions, but not other emotion regulation skills (Diedrich, Burger, Kirchner, & Berking, 2017). Interestingly, a review of the literature on the association between self-compassion and coping strategy use by Allen and Leary (2010) suggests that the association between self-compassion and the use of positive cognitive restructuring/ reappraisal is most evident, consistent with the idea that effective regulation of emotional states, including through self-compassion, limits escalation of negative affect and facilitates subsequent engagement in positive coping responses.
Experimental studies have also examined the association between self-compassion and emotional responses to stress or induced negative mood. For example, across a series of five studies with non-clinical, largely undergraduate student samples, Leary, Tate, Adams, Allen, and Hancock (2007) demonstrated that self-compassion attenuated emotional reactions to a range of stressful real, remembered, and imagined events. Such findings are consistent with another recent study examining the naturalistic relationship between selfcompassion, affect and daily stressors in 101 participants who provided mood and stressor data twice daily (Krieger, Hermann, Zimmermann, & Holtforth, 2015). This study showed that selfcompassion attenuated the effect of daily stressors on negative affect, although not positive affect, over a 2-week period. A majority of studies of self-compassion and emotion regulation to date have relied on non-clinical samples. However, one recent experimental study of 48 people meeting criteria for depression compared self-compassion with a range of other emotion regulation strategies intended to repair mood following a sad mood induction (Diedrich, Grant, Hofmann, Hiller, & Berking, 2014). This study suggested that deliberately activating feelings of self-compassion (i.e., using self-compassion as a form of emotion regulation) was more effective than a simple waiting period in reducing depressed mood following a mood induction but did not differ significantly from either acceptance or reappraisal. In a second study, conducted concurrently with the work reported here, this group considered the relationship between emotion regulation and the ability of depressed patients to benefit from a cognitive reappraisal exercise following mood induction (Diedrich, Hofmann, Cuijpers, & Berking, 2016). This study randomized participants to complete a negative mood induction followed by a preparatory acceptance induction, self-compassion induction, or a waiting period, and then a period of cognitive reappraisal, with mood changes over the course of the experimental Key Practitioner Message: • Higher levels of dispositional self-compassion are associated with selection of more adaptive cognitive emotion regulation strategies in people with a history of depressive relapse/recurrence.
• Dispositional self-compassion is also associated with greater mood repair following a mood challenge. procedure as the outcome measure. Results indicated that self-compassion, but not acceptance, significantly enhanced the effects of cognitive reappraisal compared to a waiting period. These studies focus on deliberate cultivation of self-compassion in the service of emotion regulation, as part of an experimental procedure. However, their findings suggest that further research exploring the ways in which habitual cognitive emotion regulation strategy use and dispositional selfcompassion (i.e., participants' self-reported tendencies toward selfcompassion in daily life) might interact with one another in depressed or at-risk populations, or with interventions designed to support mood repair, is warranted.

| Current studies
This paper reports two studies, one correlational and one experimental that together examine these issues in a group at risk for depression relapse/recurrence, on the basis of their clinical history of depressive episodes. We hypothesized that consistent with the findings of other recent work, dispositional self-compassion would enhance the capacity to respond to negative events and negative mood in ways that lessen its secondary negative consequences (in this paper operationalized as continuing emotional dysregulation and self-devaluation).
Study 1 explored the relationship between dispositional selfcompassion (Self-Compassion Scale [SCS]) and use of cognitive emotion regulation strategies such as positive reappraisal, positive planning, catastrophizing, and self-blame, extending previous findings by focusing on a large sample of participants with a history of recurrent major depression (three or more prior episodes) and utilizing a measure which explores habitual use of cognitive and emotion regulation strategies.
Study 2 examined the impact of individual differences in dispositional self-compassion and reported use of positive and negative cognitive emotion regulation strategies on changes in mood and selfdevaluation across an experimental mood-induction procedure. It considered the extent to which changes in mood and self-devaluation differed as a function of experimentally induced response styles, with participants encouraged to engage in mindfulness, rumination or a period of silence during the mood repair phase. It also considered the interaction between dispositional tendencies (SCS and Cognitive Emotion Regulation Questionnaire [CERQ] scores) and induced response styles in determining changes in mood and self-devaluation.
Previous research suggests that rumination sustains negative mood (Nolen-Hoeksema, Blair, & Lyubomirsky, 2008) and that mindfulness attenuates it (Keng, Tan, Eisenlohr-Moul, & Smoski, 2017). However, it is unclear how dispositional factors interact with deliberate adoption of particular mood repair strategies to determine emotion regulation or indeed whether brief experimentally induced mood repair strategies have sufficient impact to override or modify trait-like response tendencies. As a result, the examination of potential interaction effects between dispositional factors and induced mood repair strategies was exploratory. In summary, we aimed to answer the following research questions: 1. How are self-compassion and cognitive emotion regulation strategy use associated in people with a history of recurrent depression (Study 1)? 2. Do individual differences in self-compassion and cognitive emotion regulation strategy use in people at risk for depression determine levels of emotional disturbance and self-devaluative processing following mood challenge? Does exploratory analysis suggest evidence that these relationships differ according to the type of mood repair participants are encouraged to employ (Study 2)? 2 | STUDY 1: METHOD 2.1 | Participants Study 1 utilized baseline data from participants recruited to a published randomized controlled trial (Kuyken et al., 2015). Participants were recruited from urban and rural GP practices in the South West of England. Inclusion criteria for the trial were a diagnosis of recurrent major depressive disorder in full or partial remission, as assessed with the Structured Clinical Interview for DSM-IV (SCID-IV; Spitzer, Williams, Gibbon, & First, 1996) and aged 18 or older. Exclusion criteria were a current major depressive episode meeting full diagnostic criteria; co-morbid diagnoses of current substance abuse; organic brain damage; current/past psychosis, including bipolar disorder; persistent antisocial behaviour and persistent self-injury requiring clinical management/therapy. All participants were on a therapeutic dose of maintenance antidepressant medication. In total, 403 participants from the original trial sample had complete data on the SCS and the CERQ, with a further 21 participants from the original study excluded due to missing data. The overall sample comprised 306 women and 97 men with a mean age of 49·54 years (SD = 12.33). The sample was almost exclusively (99%) of Caucasian ethnicity. At the point of assessment, the mean level of depressive symptoms in the sample, as assessed by the Beck Depression Inventory Second Edition (BDI-II; see below) was 14·09 (SD = 10.00), falling just within the range of mild depressive symptoms.
The study was granted ethical approval by the NHS Research Ethics Committee and by the School of Psychology Ethics Committee, University of Exeter.

| Structured Clinical Interview for DSM-IV (SCID-IV)
The depression module of the SCID-IV was used to establish a history of depression and current depression status (Spitzer et al., 1996).

| Self-Compassion Scale (SCS)
The SCS is a 26-item self-report instrument, with each item rated on a 5-point Likert scale (1 = Almost Never to 5 = Almost Always; Neff, 2003a). It yields a total score as well as scores on six subscales: selfkindness, self-judgement, common humanity, isolation, mindfulness, and over-identification. Higher scores indicate higher levels for each respective scale, with reverse scoring of items loading onto the negatively framed subscales. Sample items include "I try to be loving towards myself when I'm feeling emotional pain" and "When times are really difficult, I tend to be tough on myself." The SCS has good test-retest reliability (r = .93) and convergent and discriminant validity . A recent psychometric evaluation broadly supports the subscales' reliability and validity in clinical samples (Neff, Whitaker, & Karl, 2017).

| Beck Depression Inventory Second Edition (BDI-II)
The BDI-II is 21-item measure, with each item scored on a 4-point scale, yielding a summary score ranging from 0 to 63. Scores of 0-13 are considered to reflect minimal symptoms of depression, 14-19 mild depression, 20-28 moderate symptoms of depression, and 29-62 severe symptoms of depression (Beck, Steer, & Brown, 1996). The measure has demonstrated excellent reliability, validity, and sensitivity to change (Beck, Steer, Ball, & Ranieri, 2010;Beck et al., 1996).

| Cognitive Emotion Regulation Questionnaire (CERQ)
The CERQ is a 36-item self-report measure of cognitive coping strategies used following a negative event or situation, with each item rated on a 5-point scale (1 = [Almost] never to 5 = [Almost] always; Garnefski, Kraaij, & Spinhoven, 2002). It provides a total score as well as scores on nine subscales: self-blame, acceptance, rumination, positive refocusing, refocus/planning, positive reappraisal, putting into perspective, catastrophizing, and other blame. Higher scores indicate higher levels for each respective scale (reverse scoring of some items is required for the total score). Sample items include "I think that I have to accept the situation" and "I am preoccupied with what I think and feel about what I have experienced." The CERQ has demonstrated adequate reliability and validity (Garnefski & Kraaij, 2007). For the purposes of the current studies, we additionally summed the positive subscales (acceptance, positive refocusing, refocus/planning, positive reappraisal, and putting into perspective) and negative subscales (self-blame, rumination, catastrophizing, and other blame) to produce two composite scores representing theoretically more and less adaptive cognitive coping responses, following Potthoff et al. (2016).

| Statistical analysis
Data were analysed using statistical software SPSS version 22 (IBM Corp., 2013). Data were investigated for outlying values, skewness, and kurtosis. There were outlying values on each of the SCS subscales with the exception of common humanity as well as on the total score. 3 | STUDY 1: RESULTS Table 1 shows the exploratory Spearman's correlation coefficients between the SCS total and facet scores and each of the CERQ subscales. There were significant positive correlations of moderate strength between the total SCS score and the CERQ subscales of positive refocusing, refocus/planning, positive reappraisal, and putting into perspective. Likewise, there were significant negative correlations between total SCS score and the CERQ subscales of self-blame, other blame, rumination, and catastrophizing, which were very weak in strength for other blame, weak in strength for rumination, and moderate in strength for catastrophizing and self-blame.

| Association between self-compassion and emotion regulation
There was no significant correlation between total SCS score and the CERQ subscale of acceptance. Summing across positive and negative CERQ subscales, there was a large positive correlation between total SCS score and positive CERQ subscales, r = 52, p < .001 and a large negative correlation between total SCS score and negative CERQ subscales, r = −.51, p < .001. All but three of the statistically significant correlation coefficients between SCS and CERQ facets (SCS self-kindness and CERQ rumination, SCS self-judgement and CERQ positive reappraisal, and SCS self-judgement and CERQ other blame) remain significant following application of a Bonferroni correction to account for multiple comparisons and retain a familywise alpha of p < .005 (requiring individual correlation coefficients to p < .008).
The above findings support previous work identifying associations between self-compassion and positive cognitive restructuring (e.g., Allen & Leary, 2010) and extend these to a clinical sample with a history of recurrent depression. They suggest that self-compassion is associated with the way that people respond to negative events and experiences. Study 2 moves beyond retrospective self-report to bring the relationship between self-compassion, cognitive emotional regulation strategy use, and responses to mood challenge under experimental control.

| STUDY 2: INTRODUCTION
Study 2 was an experimental study designed to establish whether individual differences in self-compassion and cognitive emotion regulation strategy use in people with a history of depression explained differences in mood and self-devaluation following a period of mood induction and potential mood repair, in which each participant was invited to engage in one of three different mood repair strategies. The mood repair strategies to which participants were assigned were silence (intended to allow engagement in usual emotion regulation strategies), rumination (intended to encourage engagement in analytical selffocused thinking), and mindful breathing (intended to encourage participants to decentre from thoughts and feelings and facilitate self-compassionate responses).

| Participants
Participants were drawn from individuals associated with the University of Exeter and the surrounding local community (recruited using posters), and people who had expressed an interest in participating in the PREVENT randomized controlled trial (described in methods of Study 1), but were ineligible because they had expereinced fewer than three previous depressive episodes. All participants had a history of depression in full or partial remission and scored <10 on the Hamilton Rating Scale for Depression (HAMD; J. B. W. Williams et al., 2008) to ensure that the experimental procedure did not exacerbate depressive symptoms in those currently experiencing significant residual symptoms (e.g., Kuyken, Watkins, et al., 2010). Clinical interviews were conducted by fully trained postgraduate research psychologists under supervision of a clinical psychologist (WK). Participants received £10 payment for participation, or in the case of university students, given course credits.

| Mood induction procedure
To assess responses to mood challenge, we employed the laboratory mood induction paradigm used by Segal et al. (2006) and described below. The task consisted of two parts, first, a negative mood induction and, second, a mood repair phase.

| Sad mood induction and manipulation check
To induce sad mood participants listened to sad music (Prokofiev's "Russia under the Mongolian Yoke" re-mastered at half speed) for 8 min whilst rehearsing a sad memory. Participants were free to bring to mind any sad memory they chose and to rehearse this memory for the duration of the mood induction procedure. Sad mood was assessed premood and postmood induction using a visual analogue scale (VAS) from 0 (I do not feel this way at all) to 100 (I feel this way very much or extremely), and again following the mood repair phase, described below.

| Mood repair phase
Following the sad mood induction, participants were allocated by MW and JC to one of three conditions that were hypothesized to affect emotion regulation and, hence, degree of mood repair in a group at risk for depressive relapse. The groups were matched for age and gender and comparable on a range of other baseline measures (see later).
Assignment was sequential, initially to the mindfulness and silence conditions with a third rumination condition added after study com-

| Depressed States Checklist (DSC)
The DSC assesses endorsement of self-devaluative adjectives thought to be activated at times of low mood in people at risk for depressive relapse (e.g., "abandoned," "a failure," and "pathetic"; Teasdale & Cox, 2001. Respondents indicate how far they endorsed these adjectives when their mood started to go down in the last month on a 4-point scale (0 = Not at all to 3 = Very or extremely). The measure shows good reliability and discriminant validity. We analysed a sum-score corresponding to endorsement of the 14 adjectives that are indicative of self-devaluation (following Ehring, Ehlers, & Glucksman, 2008).
Although not ostensibly a state measure, we hypothesized that reinstatement of depressogenic thinking following mood induction would lead to increased endorsement of self-devaluative adjectives and, thus, indicate increased self-devaluation at a time of low mood.

| Procedure
Participants were initially screened via telephone to assess eligibility.
Eligible participants were mailed the study information sheet and questionnaire booklet including the CERQ, SCS, and BDI-II to complete and send back/bring with them to the testing session. Following informed consent, the study procedure followed the flow depicted in Figure 1. Participants first completed the DSC, were assessed for eligibility using the SCID-IV and HAMD, and then completed the first VAS ratings (T1). All participants then completed the mood induction paradigm, followed by a further set of VAS ratings (T2). Participants then followed the instructions for their assigned mood repair condition.
Finally, all participants completed the DSC again alongside a final set of VAS ratings (T3). At the end of the study, participants were debriefed and offered some exercises to repair mood if necessary.

| Mood induction
To test the impact of mood induction and mood repair on participant's mood and DSC score, a series of repeated measures ANOVAs with time (T1, T2, T3 for mood, T1 and T3 for DSC) as within-subjects factor and condition (silence, mindful breathing, and rumination) as between-subjects factor were conducted. Main effects and interactions were followed up by Bonferroni-corrected post hoc test and simple contrasts.

This indicates that (a) the sad mood induction was successful across conditions to induce sad mood and that (b) individuals in the silence and mindful breathing conditions show reductions in sad mood between T2 and T3 (due to dissipation of negative mood or mood repair) whereas those in the rumination condition do not (see Figure 2).

| DISCUSSION
Sad mood is a normal, adaptive emotion. However, in those at risk for recurrent depression, it has developed unhelpful associations with self-devaluative beliefs and maladaptive emotion regulation strategies such as self-blame, rumination, and catastrophizing. The studies presented in this paper build on previous research which has suggested that self-compassion may be important in helping people at risk for depressive relapse/recurrence manage low mood and the activation of negative mental content and process that often accompanies it, in an adaptive way (Krieger et al., 2016;Neff, 2003aNeff, , 2003bPauley & McPherson, 2010). The findings of Study 1 extend previous research on the association between self-compassion and adaptive emotional regulation (Krieger et al., 2015;Leary et al., 2007) to a clinical sample with a history of recurrent depression, demonstrating that FIGURE 4 Correlations between self-compassion and mood change (residualized gain scores) during mood repair task in this population dispositional self-compassion, assessed by the SCS, was associated with greater endorsement with adaptive cognitive emotion regulation strategy use. Likewise, the identification of associations between the SCS and maladaptive coping responses such as self-blame and catastrophizing are also consistent with earlier research (Raes, 2010). Interestingly, the only exception to the general pattern of results was for the CERQ acceptance subscale. Higher scores on this subscale were associated, albeit weakly, with participants' reporting of both greater mindfulness and common humanity and also greater isolation and self-judgement. These findings, which appear counter-intuitive, may reflect the item content on the CERQ acceptance subscale. This subscale contains items which reflect both the non-judgemental acceptance characteristic of a more mindful orientation to experience, for example, "I think that I have to accept that this has happened" and "I think that I have to accept the situation", but also items that have a tone more characteristic of resignation or defeat "I think I cannot change anything about it" and "I think I must learn to live with it." This ambiguity in item content may explain the unexpected lack of association of the CERQ acceptance subscale with self-compassion, despite the theoretical overlap between these constructs. Overall, the results suggest that individual differences in self-compassion and its constituent facets appear to be meaningfully related to the strategies that people with a history of depression report employing to cope with difficult or stressful situations.
Study 2 examined the association between dispositional selfcompassion, use of cognitive emotion regulation strategies, and changes in mood and self-devaluation in participants exposed to a negative mood induction followed by mood repair (mindfulness, rumination, silence). The findings point to a significant role for individual differences in self compassion and negative cognitive emotion regulation strategy use in influencing responses to a mood challenge procedure among people at risk for depressive relapse/recurrence, both in terms of mood recovery (SCS) and changes in self-devaluation (SCS and negative CERQ). These findings suggest that self-compassion signifies a general ability to tolerate and regulate intense emotions, a capacity which is likely to be important to resilience and wellbeing in a highly vulnerable group.
Instructing individuals to ruminate following mood challenge sustained negative mood, and instructing them to engage in a period of silence or mindfulness was associated with reductions in negative mood. However, exploratory analyses suggested that the effects of SCS on mood and self-devaluation, and negative CERQ on selfdevaluation, were similar irrespective of how an individual was instructed to relate to their sad mood. The absence of statistically significant interactions between participants' levels of self-compassion or cognitive emotion regulation and the effects of the different mood repair strategies can possibly be explained by the small effect size and the sample size (e.g., Alexander & DeShon, 1994). The sample required to render an interaction effect of the size obtained in this study (e.g., R 2 = .02) statistically significant would need to be much larger (e.g., N = 395) which would have made our experimental study unfeasible. It would therefore be premature to conclude that the association between type of mood regulation and reported mood or self-devaluation is not moderated by dispositional self-compassion or emotion regulation and future large scale multicentric replications should test this assumption.

| Limitations
The studies reported in this paper should be interpreted in the light of a number of factors. First, there is a need to consider the best way to interpret the effects of the different mood repair strategies on persistence of negative mood. One possibility is that rather than the mindfulness and silence conditions producing active mood repair, reductions in negative mood in these two conditions may simply reflect natural recovery. However, the mindfulness condition was associated with significant reductions in self-devaluation, whereas in the silence condition there was no significant change. This suggests some differential action of the two mood repair strategies. One possibility is that instructions to engage in a mindful breathing practice may provide distraction from self-devaluative thoughts, or through the emphasis on acceptance of mind wandering and sustained attention on the breath, may have limited their proliferation and persistence.
Future work which includes a distraction condition as well as mindfulness, rumination, and silence conditions would help to address this issue.
A second issue concerns the fact that in an ideal study design, self-devaluation would have been measured on three occasions; prior to the mood induction and both prior to and following the mood repair phase. Concerns about the impact of multiple repeated administration of the DSC meant that it was only included at the first and third assessment points. However, since dispositional self-compassion may influence both the extent to which mood induction activates selfdevaluative cognitions and the extent to which such cognitions diminish during mood repair, a design which allowed these two effects to be separated would have been preferable and would be an interesting topic for future research.
A third issue concerns the nature of the sample in Study 2, which was composed of individuals with a history of depression but low levels of residual symptoms. Our findings therefore illuminate cognitive processes in those at risk of depressive relapse/recurrence rather than those at risk of a first episode of depression. Models of cognitive reactivity suggest that habitual response patterns are established across depressive episodes and, particularly, in the case of self-devaluation, it is likely that it is these habitual response patterns that are observed. Thus, it is not clear to what extent our findings would also generalize to the relationship between self-compassion and responses to mood induction in those who had not yet experienced a depressive episode but were vulnerable. Likewise, by excluding those with high levels of residual symptoms (for ethical reasons, in a design with negative mood induction), we may have excluded those most likely to show cognitive reactivity in response to the mood induction paradigm, thus attenuating effects. Our sample also contained a majority of female participants, and so it is unclear whether the findings would generalize to majority male samples.
Finally, random assignment was not used in Study 2. Thus, whilst the three experimental groups did not differ in age, gender, baseline residual depressive symptoms, baseline CERQ scores, or baseline SCS, it is possible that there may have been undetected differences between the populations and a fully randomized design would have strengthened the findings.

| CONCLUSIONS
Although self-compassion can be conceptualized as an individual difference variable, it is also a capacity that can be enhanced through a range of psychological therapies (e.g., Gilbert, 2009;Kabat-Zinn, 2013;Segal, Williams, & Teasdale, 2013). There is evidence that development of self-compassion is one crucial aspect of the change process in mindfulness-based stress reduction (Shapiro, Brown, & Biegel, 2007) and mindfulness-based cognitive therapy (Kuyken, Watkins, et al., 2010); and studies suggest that in interventions that train selfcompassion, such training is associated with a range of positive outcomes (Hofmann, Grossman, & Hinton, 2011;Kuyken, Watkins, et al., 2010). Our findings support the idea that self-compassion supports adaptive responses to mood challenge including more rapid mood recovery, greater engagement in positive, proactive problem solving strategies, and less engagement in maladaptive responses to negative experiences. It would be advantageous for future work to examine whether such associations translate into therapeutic contexts in which self-compassion is deliberately enhanced, either explicitly or implicitly, and thus the extent to which engagement in positive coping strategies accounts for some of the beneficial effects of such approaches on mental health outcomes.
