Construction and Validation of the Iranian scale of Midlife Challenges



The aim of the present study is to construct an instrument for research in the field of middle age development that It can help in launching various researches in this field. After reviewing various theories about the middle age development, 12 areas of developmental challenges were identified and based on them, 66 questions (on average 5.5 questions per each domain) were designed. At first, the questions were reviewed by four experts in the field of developmental psychology in terms of content validity and after some changes in the wording of some questions, were administrated on 398 subjects (204 women and 194 men) from 22 districts of Tehran residents between the ages of 40 to 65 years. The factor analysis showed that the scale consisted of 6 factors which respectively include; job satisfaction, leisure without pleasure, concerns, marital dissatisfaction, interaction with the next generation and social responsibility. Statistics of the internal consistency of the questionnaire showed that most of the subscales have desirable reliability. As a result, the questionnaire is appropriate for applying in the researches on middle age developmental challenges.
