The Subjective Impact and Timing of Adversity Scale: A Feasibility Study Using Cross-Sectional and Longitudinal Data

Area of Science:

• Psychology
• Psychiatry
• Developmental Psychology

Background:

• Childhood psychological adversity is a significant risk factor for mental health issues.
• Existing measures may not fully capture the nuances of adversity exposure.
• A comprehensive tool is needed to assess the occurrence, impact, and timing of adversity.

Purpose of the Study:

• To assess the feasibility of the Subjective Impact and Timing of Adversity Scale (SITA).
• To evaluate the SITA's reliability and validity in measuring psychological adversity.
• To explore the relationship between adversity exposure and psychiatric diagnoses.

Main Methods:

• Utilized data from participants previously assessed at ages 14 and 21.
• Administered the SITA across online and interview formats.
• Analyzed internal consistency, convergent validity, and group differences based on psychiatric diagnoses.

Main Results:

• The SITA demonstrated acceptable internal consistency across most domains.
• SITA scores showed meaningful correlations with other psychological measures, supporting convergent validity.
• Individuals with lifetime psychiatric diagnoses reported significantly higher SITA domain scores.

Conclusions:

• The SITA is a viable tool for assessing the subjective impact and timing of childhood adversity.
• Both the subjective impact and timing of adversity appear important for psychiatric outcomes.
• Further research with larger samples is recommended to confirm these findings.
