The purpose of the study was to develop an indigenous scale to measure frustration and to estab1ish its psychometric properties. In the first phase, the item pool of 70 items was generated by an in-depth review of literature, and semi-structured interviews. Experts evaluation were taken to identifying the unclear, inappropriate, and redundant items.17 items were excluded which were redundant, overlapped, or poor worded. Pilot study was conducted (n=20) on the preliminary scale to measure its face validity. In the second phase, internal consistency and dimensionality of the scale was empirically measured through Exploratory Factor Analysis (N=300). Three factors (Agitation, Liability, and Disgruntled) emerged. In the third phase, to confirm the factor structure of the scale the Confirmatory Factor Analysis (N=300)was run. Psychometric properties were established (α= .93). In the final phase, the convergent and discriminant validity was established by using Basic Psychological Need Satisfaction and Frustration Scale (Vansteenkiste, 2015). Finally, indigenous frustration scale for emerging adults was constructed. |
