Health-Risk Behaviours (HRBs) are significantly associated with avoidable mortality in adolescents, and preventing HRBs requires an adequate understanding of related factors. Among associated factors, emotion regulation difficulties may impact youths’ engagement in HRBs. Researchers explored the relation of emotion regulation with HRBs; however, specific emotion regulation difficulties for less severe and more prevalent HRBs, such as self-harming behaviour, risky-driving, violence, unhealthy dietary behaviour, and poor adherence to prescribed medication, has not been much explored. The current study aimed to explore the predictability of adolescents’ specific difficulties in emotion regulation in relation to their engagement in HRBs. For this purpose, six different HRBs, that is, self-harm, violence, risky-driving, unhealthy dietary behaviour, inadequate physical activity, and lack of medication adherence, were studied. A total of 617 (Males = 356) adolescents (Mage = 15.77) from five districts of Punjab state (India) provided required information on standardised self-report measures. The data were subjected to regression analysis, and the findings show that the participants who scored high on emotion regulation difficulties reported engagement in HRBs more than their counterparts. Some specific difficulties are more important than others for different forms of HRBs. It implies that the intervention programmes targeting specific HRBs should address specific facets of emotional dysregulation.

While dialectical behaviour therapy (DBT) appears efficacious in reducing suicidal and self-harming behaviour, it is unclear whether DBT reduces emotion regulation (ER) difficulties, a purported mechanism of change of treatment. This review aims to investigate and evaluate the current evidence to understand the effectiveness of DBT in improving ER difficulties. A qualitative synthesis of studies investigating the effectiveness of DBT on self-reported ER difficulties as measured by the Difficulties in Emotion Regulation Scale (DERS) was performed, identifying eligible studies using PsycINFO, PubMed, MEDLINE and EMBASE databases. Fourteen studies were identified. Current evidence indicates that DBT does not show consistent benefits relative to existing psychological treatments in improving ER difficulties. The literature is compromised by significant methodological limitations increasing risk of bias across study outcomes. Furthermore, high variability across DBT programs and a lack of investigation regarding adherence and participant engagement within interventions was observed. Further research is needed in order to conclude regarding the effectiveness of DBT in improving ER difficulties. Consistent use of active treatment conditions, greater standardisation of DBT-based interventions, in addition to further examination of participant engagement level in DBT-based interventions in the long term may assist understanding as to whether DBT improves ER difficulties.
