Validity of Experiential and Reflective Self-knowledge Scales: relationships with basic need satisfaction among Iranian factory workers.

This study examined the validity of Experiential and Reflective Self-knowledge Scales in a sample of Iranian factory workers. Both scales were administered to 321 male and 12 female workers (M age= 35.6 yr., SD= 8.9) along with the Basic Need Satisfaction at Work Scales, the Work Climate Questionnaire, and measures of Perceived Stress and Self-esteem. Scores on the two self-knowledge measures correlated with all other variables consistent with the claim of Self-determination Theory that self-insight is associated with a more complete satisfaction of basic needs. In a number of multiple regression analyses, Reflective and Experiential Self-knowledge combined to explain variance in other measures. These data further supported the validity of the two new Self-knowledge Scales.
