Abstract:
This study investigated the effect of social skill training (SST) intervention on social 
anxiety, self-esteem, and university adjustment among university-level students in 
Bangladesh. Utilizing a quasi-experimental randomized waitlist control design, 
participants were assigned to either the experimental group (EG), which received a 
four-week SST intervention, or the waitlist control group (WCG), which waited four 
weeks before receiving the intervention. Assessments were conducted at pretest, post
wait test, post-test, and one-month follow-up tests to evaluate changes in social 
anxiety, self-esteem, and university adjustment. This study was conducted across 
eight institutions, including three public universities, three private universities, and 
two university-affiliated colleges, from January to April 2023. A total of 172 students, 
divided into experimental (n = 93) and waitlist control (n = 79) groups participated in 
the study. The participants were recruited through notices and underwent screening 
for social anxiety disorder. The intervention consisted of eight group sessions 
delivered over four weeks, focusing on verbal, nonverbal, and assertive 
communication skills. The study employed an eligibility measure i.e., the Severity 
Measure for Social Anxiety Disorder (Social Phobia)-Adult, and four outcome 
measures, including the Brief Version of the Fear of Negative Evaluation (BFNE) 
Scale, Inventory of Interpersonal Situations (IIS), Bangla version Rosenberg Self
Esteem Scale (RSES), and Student Adaptation to College Questionnaire (SACQ). The 
English versions of these outcome measures were translated and culturally adapted to 
the Bangladeshi context using TRAPD model and validated through a confirmatory 
factor analysis (CFA) using partial least square structural equation modeling (PLS
SEM). Data analysis using SPSS Statistics 27 and SmartPLS 4, included independent 
sample t-tests, one-way repeated measures ANOVA, repeated measures MANOVA, 
and mediation modeling. Results indicated that the SST intervention significantly 
reduced social anxiety and improved self-esteem and university adjustment in the EG 
compared to the WCG with moderate to large effect sizes. Both experimental and 
waitlist control groups experienced significant improvements in social anxiety (fear of 
negative evaluation, IIS discomfort), self-esteem, and university adjustment with large 
effect sizes. The interaction effect indicates that the experimental group showed 
greater improvements in studied variables from the pretest to post-test with large 
effect sizes. Additionally, self-esteem was found to mediate the relationship between 
social anxiety (fear of negative evaluation) and university adjustment. Therefore, SST 
is an effective intervention for reducing social anxiety and improving self-esteem and 
university adjustment among university students in Bangladesh. The study highlights 
the importance of addressing social anxiety and enhancing self-esteem to facilitate 
xviii 
better adjustment in university. Implications for practice and future research 
directions are discussed.
