Korean Version of the Interpersonal Competence Questionnaire (K-ICQ)
Časové okno: Baseline, immediately post-intervention (at 8 weeks), and 1-month follow-up (at 12 weeks)
|
The Korean Version of the Interpersonal Competence Questionnaire (K-ICQ) is a 31-item self-report measure of interpersonal competence.
Each item is rated on a 5-point Likert scale from 1 (poor) to 5 (extremely good).
The total score sums all items and ranges from 31 to 155.
Higher scores indicate greater interpersonal competence, which is a better outcome.

Social Skills Knowledge Test
Časové okno: Baseline, immediately post-intervention (at 8 weeks), and 1-month follow-up (at 12 weeks)
|
The Social Skills Knowledge Test is an investigator-developed knowledge test created to objectively measure acquisition of the social skills content taught in the intervention.
It consists of 21 items (multiple-choice and true/false) covering seven domains that correspond to the session curriculum: relationship formation skills, conversation skills I, conversation skills II, assertion skills, conflict management skills, dating skills, and workplace skills, with 3 items per domain.
Each item has an unambiguously correct answer and is scored 1 (correct) or 0 (incorrect).
The total score is the sum of correct responses and ranges from 0 to 21.
Higher scores indicate greater knowledge of social skills, which is a better outcome.

LINK Skill-Specific Behavior Coding System (LINK-BSC) performance score
Časové okno: Baseline and post-intervention (at 8 weeks)
|
The LINK Skill-Specific Behavior Coding System (LINK-BSC) is an investigator-developed observational coding system for the social skills explicitly taught in the intervention.
Two structured role-play scenes are coded: an interaction with an unfamiliar peer (9 indicators) and a face-to-face assertion and conflict-management task (9 indicators), 18 indicators in total.
Each indicator is coded as 1 (displayed) or 0 (not displayed).
The occurrence score is the number of indicators displayed divided by the number of applicable indicators, expressed as a percentage from 0 to 100.
Higher scores indicate a broader repertoire of the trained skills, which is a better outcome.

LINK Skill-Specific Behavior Coding System (LINK-BSC) proficiency score
Časové okno: Baseline and post-intervention (at 8 weeks)
|
The LINK Skill-Specific Behavior Coding System (LINK-BSC) is an investigator-developed observational coding system for the social skills explicitly taught in the intervention.
Two structured role-play scenes are coded: an interaction with an unfamiliar peer (9 indicators) and a face-to-face assertion and conflict-management task (9 indicators), 18 indicators in total.
Each indicator is first coded for occurrence (1 = displayed, 0 = not displayed) and then for proficiency on a 3-point scale from 0 to 2. The proficiency score is the sum of the proficiency ratings across all 18 indicators divided by twice the number of applicable indicators, expressed as a percentage from 0 to 100.
Indicators for which no opportunity was provided are excluded from the denominator.
Higher scores indicate more proficient use of the trained skills, which is a better outcome.

Social Performance Rating Scale (SPRS)
Časové okno: Baseline and post-intervention (at 8 weeks)
|
The Social Performance Rating Scale (SPRS) is an observer-rated measure of the molecular verbal and nonverbal quality of social performance during structured role-plays.
Two scored role-play scenes are administered - an interaction with an unfamiliar peer (approximately 3 minutes) and a face-to-face assertion and conflict-management task (approximately 4 minutes) - preceded by an unscored 1-minute practice scene.
In each scored scene, trained raters blinded to group allocation and assessment time point rate five domains: gaze, vocal quality, length of speech, discomfort, and conversational flow.
Each domain is rated on a 5-point scale from 1 (very poor) to 5 (very good), with the discomfort item reverse-scored so that higher values indicate less discomfort.
Each scene score ranges from 5 to 25, and the total score across the two scored scenes ranges from 10 to 50.
Higher scores indicate more appropriate and positive social performance, which is a better outcome.

|
The Korean version of the Social Interaction Anxiety Scale-Social Phobia Scale Short Form (K-SIAS-SPS-SF) is a single 14-item self-report measure of social anxiety.
Its items were derived by exploratory factor analysis of the pooled 40-item set of the Social Interaction Anxiety Scale and the Social Phobia Scale, and the resulting instrument is administered and scored as one scale comprising three correlated factors: social interaction anxiety (5 items), fear of overt evaluation (6 items), and fear of attracting attention (3 items).

A single total score is obtained by summing all 14 items and ranges from 0 to 56, with a total score of 22 or higher indicating probable social anxiety disorder.
Higher scores indicate greater social anxiety, which is a worse outcome.
