Construct and Psychometric Properties of a New Version Quality of Life Scale Based on Choice Theory

Abstract

BACKGROUND: Choice theory, as a psychopathological model, postulated five basics, genetically and universally, needs. Accordingly, the rate of everybody happiness and quality of life is depended on the number of his needs fulfilling. Although some scales have been constructed to assess basic needs, they have proposed unity of needs for all human.
 AIM: The present study was designed to construct a new scale, considering individualisation needs for each person; quality of life scale based on choice theory (QOLSCT).
 METHODS: Using cluster sampling, six hundred (49% female and 51% male) postgraduate students were selected. One hundred fifty participants also filled SF-36 and GHQ, and 80 participants refilled QOLSCT with four weeks’ interval again.
 RESULTS: Cronbach’s alpha, split-half and test re-test (one month) reliability scores were 0.78, 0.75, and 0.92 successively. The correlation between items and total scores range from 0.36 to 0.72, all with P values ≥ 0.0001. Confirmatory factor analysis showed satisfactory values of goodness-of-fit indices, RMSEA, CFI, NFI and GFI were, 0.05, 0.99, 0.99 and 0.99 respectively. Convergent and divergent validity also showed significant correlations.
 CONCLUSION: The result of the present study showed that the new version of quality of life scale based on choice theory could be confirmed. The good level of reliability, fairly goodness of fit indexes, and very good convergent validity support this idea.

A Randomized Controlled Trial of Group Reality Therapy in Attention Deficit Hyperactivity Disorder and Oppositional Defiant Disorder in adolescents

“…Since choice theory emphasizes leisure activities and basic needs satisfaction, it has a remarkable positive impact on the patients, emotions, and sense of wellbeing. This finding is also in line with other research about the quality of life affecting by reality therapy (7).…”

“…Reality therapy improves internal control, which helps us to achieve our goals by managing our behavior, as opposed to external control, which focuses on controlling others. Besides, it illustrated the significant effect of our positive behavior and thinking on our feeling, which leads to improvement of mental health and reduction of anxiety and mood disorders (6,7). In previous studies, the effects of reality therapy on adults have been demonstrated.…”

“…In previous studies, the effects of reality therapy on adults have been demonstrated. Improving the quality of life and self-esteem, and having control over behaviors and consequently on emotions are cases in point (7)(8)(9)(10). Moreover, it was effective in increasing happiness and the sense of wellbeing (11).…”

Coping styles in HIV positives and HIV negatives

“…In this study, it was assumed that what led people to a successful or unsuccessful life was how they analysed different situations and their choices, as Glaser believed [ 1 ]. Based on this assumption, we selected two groups of people with different lifestyles who should indicate the difference between the two lifestyles.…”

“…"What we are today is the result of our past choices" [ 1 ] William Glaser, psychologist and the founder of Choice theory believed that the basic difference between humans is in their power of choice. The Choice theory leads us to the most fundamental human cognition.…”
