The Japanese Translation of the Meaning in Life Questionnaire-Short Form: Reliability and Construct Validity

Abstract

The purpose of this study was to evaluate the reliability and construct validity of a Japanese translation of the Meaning in Life Questionnaire-Short Form (MLQ-SF-J), a brief self-report measure of the presence of meaning in life. Data were collected from two samples of 382 Japanese college students (177 women, 205 men; mean age = 20.92 years, SD = 0.66) and 407 Japanese adult workers (196 women, 211 men; mean age = 38.83 years, SD = 9.88). Exploratory factor analysis clearly supported the expected one-factor structure of the MLQ-SF-J in both samples. The MLQ-SF-J was found to have good internal consistency reliability in both samples (Cronbach's alphas = 0.80 and 0.86) and 4-week test-retest reliability in the student sample (r = 0.70). As expected, moderate correlations with hedonic well-being scores and high correlations with eudaimonic well-being scores were generally found in both samples. Correlations between scores on the MLQ-SF-J and a purpose in life scale were also high, as expected. The MLQ-SF-J was found to be a reliable and valid measure useful for a large-scale research on purpose in life in the Japanese population.

The impact of supply chain relationship quality on knowledge sharing and innovation performance: evidence from Chinese manufacturing industry

“…Content validity is assumed to exist because the scales were constructed according to the literature and were pretested and modified based on the comments and suggestions from the key informants. This study tests the construct validity of the scale with the confirmatory factor analysis (Sumi, 2019). Construct validity is accepted when the absolute values of factor loading are higher than 0.4 (Crick and Crick, 2019).…”

Validation study of the Gratitude Questionnaire–Six Item Form in a Venezuelan general population sample of young adults

“…The evidence presented highlights the importance of studying the construct of gratitude in the field of psychology and health sciences, previous studies have indicated the relationship of the construct to mental health outcomes, for example, affectivity, well-being, prosociality, positive emotions, flourishing, optimism and personality, happiness, problem-focused and social support strategies (5,6,10,14,(15)(16)(17)(18); while gratitude has been inversely associated with indicators of distress and even possible psychopathology, including negative emotions and affectivity, depression, anxiety and stress (6,14,15,18). All the previous information justifies the development of this research.…”

“…The GQ-6 structure has been examined in Asia, Europe, and Latin America. In 409 students, Sumi found a single dimension through exploratory and confirmatory factor analyses (6), results replicated in Chile by Carmona-Halthy et al, who obtained a single factor explaining about 66 % of the variance using principal components analysis in 602 participants (7). Hudecek et al applied a confirmatory factor analysis after administering the GQ-6 to 508 Germans, detecting an appropriate fit by eliminating the sixth item (8).…”

“…The six-item model was satisfactorily reproduced in an adult group; however, it was necessary to eliminate the sixth item in an adolescent sample to achieve adequate properties (15). About construct validity, Sumi identified positive correlations with the Satisfaction with Life Scale (SWLS), the Scale of Positive and Negative Experience (SPANE), and the Flourishing Scale (FS-8), but inverse associations with the negative dimensions of the SPANE (6). Similarly, Langer et al detected associations between the Positive and Negative Affect Schedule (PANAS) and the Subjective Happiness Scale (SHS) (15).…”

“…In Germany, Hudecek et al encountered appropriate values with the same statistics (8). Sumi examined the temporal stability finding a significant association between the two measurements, optimum alpha coefficients at each point, and elevated corrected item-total correlations (6) (11), while Balgiu identified a satisfactory Cronbach's Alpha in a sample of 250 Romanian students (19). All the other consulted references reported acceptable indices (10,12,13,(16)(17)(18).…”
