Development and validation of a social functioning scale, the Social Adaptation Self-evaluation Scale

Area of Science:

• Psychiatry and Behavioral Sciences
• Clinical Psychology
• Pharmacology

Background:

• Depression significantly impairs social functioning, necessitating robust assessment tools.
• Existing measures may not fully capture patient-reported social motivation and behavior.
• Selective noradrenaline reuptake inhibitors (NARIs) are a class of antidepressants targeting specific neurotransmitter pathways.

Purpose of the Study:

• To introduce and validate the Social Adaptation Self-evaluation Scale (SASS) for assessing social functioning in depression.
• To evaluate the scale's psychometric properties, including validity, reliability, and sensitivity to change.
• To explore the factor structure and identify patient clusters based on SASS responses.

Main Methods:

• The Social Adaptation Self-evaluation Scale (SASS), a 21-item instrument, was developed.
• Validation involved a general population survey (N=4000) and two controlled trials (N=549) comparing reboxetine (NARI) with placebo/fluoxetine in major depression.
• Multivariate analyses were employed to determine the scale's factor structure and identify patient clusters.

Main Results:

• The SASS demonstrated strong validity, reliability, and sensitivity to change in depressed patients.
• Multivariate analyses revealed three principal factors and five distinct patient clusters.
• The scale effectively captures patient perspectives on self/environment and social motivation/behavior.

Conclusions:

• The Social Adaptation Self-evaluation Scale (SASS) is a simple, valid, and reliable tool for evaluating social functioning in depression.
• SASS provides valuable insights into patient-reported social motivation and behavior, complementing existing assessments.
• This scale can facilitate the development of novel antidepressants with specific effects on social functioning in depressed individuals.
