Development and validation of the Mental Health Promotion Scale.

Purpose: This study aimed to develop and validate a scale that assesses adults' mental health promotion abilities.

Design And Methods: This study was conducted in Istanbul from October 2016 to May 2018. Three rounds of the Delphi method were conducted to develop the scale.

Findings: After the third Delphi round, the experts reached a consensus on 93 scale items. Forty-six items were excluded from the scale based on exploratory factor analysis (EFA) results. In the last EFA of the 47-item scale, a 12-factor construct was found with an eigenvalue >1 that explained 64.3% of total variance. The overall Cronbach's alpha of the scale was .93.

Practice Implications: This scale can be used to assess adults' mental health promotion abilities.
