Psychometric properties of the Temporal Satisfaction with Life Scale among Turkish people

Abstract

OBJECTIVES:The determinants of subjective well-being have been largely investigated in recent years. According to Pavot and Diener who have developed TSWL (Temporal Satisfaction with Life Scale), to assess the life satisfaction level of an individual according to temporal factors, subjective well-being is composed of two constructs: an emotional or affective component (i.e. positive and negative affects) and a conceptual or cognitive component (i.e. satisfaction with life, marriage, work, and leisure). The aim of this study was to adapt the Temporal Satisfaction with Life Scale into Turkish (TSWLS-T) and examine the reliability and validity of this new Turkish version. METHODS: The study was conducted in four phases with randomly chosen 236 participants (113 females, 123 males) and the mean age of sample was 38.6 ± 12.5 years. Cultural adaptation was implemented according to the internationally suggested method and a pretest was administered to examine the language equivalence. Since the scale had high levels of language equivalence, validity and reliability studies were conducted. For construct validity, confirmatory factor analysis was employed. The Satisfaction with Life Scale (SWLS) was used in order to evaluate the validity of TSWLS-T, since internal consistency (Cronbach's alpha and intra-class coefficients) and test-retest analysis were employed to estimate instrument reliability. RESULTS:The TSWLS-T demonstrated acceptable internal consistency, with a Cronbach's alpha of 0.87 for the total scale and ranging between 0.76 and 0.88 for the subscales. The test-retest reliability was also satisfactory, with intra-class correlation coefficients of 0.81 for the total scale and ranging between 0.61 and 0.74 for the subscales (p < 0.01). Fit indices of the model supported the factor structure. However, the 1st, 5th, and 11th items in scale (past, present, and future) showed a series of problems. With these items excluded, the 12-item model provided a better fit to the data than the 15-item model while the factor structure remained almost unchanged. The author recommends that the 12-item TSWLS be used to measure temporal life satisfaction. CONCLUSIONS: The TSWLS-T is a valid and reliable measure to assess life satisfaction in Turkish.

The Psychometric Properties of the Turkish Version of the Riverside Life Satisfaction Scale–Adult Form

“…In addition, although individual and cultural differences affect the results, it is possible to evaluate the LS of an individual by measuring the domain satisfaction (work, friendship, health, etc. ;Akyürek et al, 2019). Consequently, the Riverside Life Satisfaction Scale (RLSS) was developed by Margolis et al (2019).…”

An Evaluation of the Psychometric Properties of the Temporal Satisfaction With Life Scale

“…In addition to having been used less often than the SWLS, the TSWLS's psychometric properties have rarely been investigated. Specifically, only eight studies, including the original study by Pavot et al ( 1998 ), have investigated the psychometric properties of this scale, and this has been across vastly different cultures and languages in the different countries of Turkey (Akyurek et al, 2019 ), Canada (McIntosh's, 2001 ), China (Ye, 2007 ), Germany (Trautwein, 2004 ), Spain (Tomás et al, 2016 ; Carrillo et al, 2021 ), Switzerland (Proyer et al, 2011 ), United-States (Pavot et al, 1998 ), and in different populations, such as undergraduate students (e.g., McIntosh's, 2001 ), adults (e.g., Akyurek et al, 2019 ), and older adults (e.g., Carrillo et al, 2021 ). Moreover, of those studies, only Pavot et al ( 1998 ) and McIntosh's ( 2001 ) were conducted using the original English version; all other studies used various non-English adaptations of the scale (i.e., Chinese, German, Spanish, Swiss, Turkish).…”

“…Their results supported a three-factor structure which includes all 15 original items. The Turkish adaptation of the scale was found to have a better fit with the first item of each five-item subscale removed, resulting in a 12-item measure (Akyurek et al, 2019 ), whereas the Chinese adaptation was found to have a better fit with the first and last items of each 5-item subscale removed, with then each subscale resulting in 3-items and in a 9-item measure (Ye, 2007 ). Thus, it appears there are unresolved issues regarding the replicability of the validity of the scale structure and optimal number of items.…”

“…Thus, it appears there are unresolved issues regarding the replicability of the validity of the scale structure and optimal number of items. Regarding reliability, internal consistency of the scale has been reported as good (Trautwein, 2004 ) and alpha coefficients have ranged from 0.87 to 0.93 (Pavot et al, 1998 ; Tomás et al, 2016 ; Akyurek et al, 2019 ; Carrillo et al, 2021 ). For the subscales, good internal consistency has also been reported with alpha coefficients ranging from 0.76 to 0.93 (Pavot et al, 1998 ; McIntosh's, 2001 ; Proyer et al, 2011 ; Tomás et al, 2016 ; Akyurek et al, 2019 ; Carrillo et al, 2021 ).…”
