The correlation between emotional dysregulation, adult attachment, aggression orientation, and trauma symptoms with the occurrence of NSSI was explored. An intervention was applied to selective individuals engaging in NSSI.

For Phase I of the data collection procedure, the authority of the respective educational institutions from each of the five zones mentioned in Kolkata was approached, and permission will be sought. Prevalence studies conducted worldwide reveal that the prevalence of NSSI among the community or student population is roughly 30-31%. Of the 920 participants, the ones detected with the presence of NSSI were selected based on the information schedule, FASM questionnaire, and BPRS (to screen out individuals with psychotic symptoms). On these selected students engaging in NSSI, the scales for the other respective variables were administered to explore the association between NSSI and these variables. Suggested statistical analyses for this phase were descriptive statistics like frequencies, percentages, means and standard deviation, and inferential statistics like Chi-square, t-test, ANOVA, MANOVA, and predictive statistics like binomial regression.

For Phase 2, firstly the participants who significantly engage in NSSI and also have significant symptoms of psychological trauma were randomly allocated to either of the two treatment arms. One clinical group consisted of intervention by trauma-focused CBT (TF-CBT), whereas the other treatment group comprised only supportive therapy and basic emotional regulation training. The participants in the clinical treatment group were provided with a brief report and were also informed about the expected outcome of TF-CBT in the alleviation of the symptoms. An additional consent form was provided to the young adult students who engaged in NSSI and also scored significantly higher in the TSC-40 and volunteered for this intervention program. These individuals were intervened by application of TF-CBT, spanning over an average number of 12-18 sessions across a span of 3-6 months, in contrast to the supportive therapy treatment group. The statistical analyses for the pre-intermediate-post measures were done with non-parametric statistics based on pre-post measures of TSC-40, BDI, BAI and FASM.
