Acceptance and mindfulness-based interventions (A/MBIs) are recommended for people with mental health conditions. Although there is a growing evidence base supporting the effectiveness of different A/MBIs for mental health conditions, the economic case for these interventions has not been fully explored. The aim of this systematic review was to identify and appraise all available economic evidence of A/MBIs for the management of mental health conditions. ⋯ The findings of the review provide information that may be relevant to mental health service commissioners and decision-makers as all economic evidence available on acceptance and mindfulness-based interventions for mental health conditions is summarized. Evidence relating to the cost-effectiveness and cost-saving potential of acceptance and mindfulness-based interventions is focused mainly on depression and emotional unstable personality disorder to date. Heterogeneity in the specific forms of acceptance and mindfulness-based interventions may limit generalizability of the findings. The number of health economic evaluations relating to acceptance and mindfulness-based interventions remains relatively small. Further research in this area is required.

Randomized Controlled Trial
Brief group-based acceptance and commitment therapy for stroke survivors.
To date, the efficacy of acceptance and commitment therapy (ACT) for stroke survivors has not been established. The aim of this study was to evaluate the efficacy of group-based ACT for stroke survivors in comparison with treatment as usual (TAU) controls. ⋯ Acceptance and commitment therapy (ACT), delivered didactically to groups of stroke survivors, proved feasible and acceptable. ACT had benefits, relative to treatment as usual, for depression, health status, and hope. Several secondary outcome variables did not show dependable benefit for ACT: anxiety; health-related quality of life; and mental well-being. Results should be treated as preliminary as the sample size was small, blinding was not possible, concomitant treatments were not monitored, and there was no attention control condition. Despite these limitations, group-based ACT merits further study as a potentially effective intervention.

Rates of self-harm and suicide are increasing in young people. The literature suggests that individuals who identify with alternative subcultures (e.g., Goth) may be at a greater risk. ⋯ The review supports the suggestion that those who identify as belonging to an alternative subculture may be at a higher risk of self-harm and suicidal behaviour. It also presents preliminary evidence that alternative affiliation predicts self-harm over time, and that this effect holds whilst adjusting for a number of likely confounders. The findings highlight the importance of increasing the awareness of the victimization and potential risk that these groups hold and suggests areas for intervention in health, educational, and social services. The review does not, however, indicate specifically what it is about alternative subculture affiliation (or alternative music preference) that could contribute to the risk of self-harm. Consequently, studies with a greater focus on mechanisms are needed. Methodological limitations (e.g., cross-sectional studies, small sample of 'alternative' participants, westernized samples) restricted the reliability and validity of the results which impacted on the extent to which the findings could be generalized more widely.

Depression is characterized by a range of systematic negative biases in thinking and information processing. These biases are believed to play a causal role in the aetiology and maintenance of depression, and it has been proposed that the combined effect of cognitive biases may have greater impact on depression than individual biases alone. Yet little is known about how these biases interact during adolescence when onset is most common. ⋯ A combination of biases was a better predictor of depression symptom severity than individual biases. Interpretation and self-evaluation were better predictors of depression symptom severity than recall. Negative self-evaluation was the strongest individual predictor of depression symptom severity. Negative self-evaluation was able to classify depressed from non-depressed adolescents. The cross-sectional design of the study precludes any conclusions about the potential causal role of these variables. Different tasks were used to assess different types of cognitive bias meaning that the possible linear operation along an information processing 'pathway' could not be examined.

Veterans and military service members have increased risk for post-traumatic stress disorder (PTSD) and consequent problems with health, psychosocial functioning, and quality of life. In this population and others, shame and guilt have emerged as contributors to PTSD, but there is a considerable need for research that precisely demonstrates how shame and guilt are associated with PTSD. This study examined whether a) trauma-related shame predicts PTSD severity beyond the effects of trauma-related guilt and b) shame accounts for a greater proportion of variance in PTSD symptoms than guilt. ⋯ Trauma-related shame and guilt explained almost half of the observed variance in PTSD symptom severity among this sample of US military veterans and service members. Trauma-related shame and guilt each made a unique contribution to PTSD severity after accounting for the similarity between these two emotions; however, shame was particularly associated with increased PTSD severity. These results highlight the importance of assessing and addressing trauma-related shame and guilt in PTSD treatment among military populations. We suggest that emotion- and compassion-focused techniques may be particularly relevant for addressing trauma-related shame and guilt. Limitations of the study Cross-sectional data does not allow for determination of causal relationships. Although sufficiently powered, the sample size is small. The present sample self-selected to participate in a study about stress and emotions.
