Revision and adaptation of the fourth version of the Spiritual Intelligence Self-Report Inventory (SISRI-24) into Latvian

Description

Objectives. Research interest in spirituality and religiosity within psychology is growing globally. However, there is a lack of validated assessment tools to measure constructs related to spirituality, including spiritual intelligence, particularly in Latvia.

The aim of the study was to adapt the revised Latvian version (Regzdiņa & Mārtinsone, 2019) of the Spiritual Intelligence Self-Report Inventory (SISRI-24, King & DeCicco, 2009) that is designed to measure spiritual intelligence.

Materials and methods. Based on prior findings indicating inconsistencies (Regzdiņa & Mārtinsone, 2019), four items (6, 8, 9, and 24) were revised and translated in Latvian. A total of 416 participants aged 19–87 (M = 41.54, SD = 13.28; 17% male) completed the updated Latvian SISRI-24 and sociodemographic questions. The entire SISRI-24 was adapted for use in Latvia (24 items, each rated on a 5-point Likert scale (0–4).

Results. The internal consistency of the scale is very high (α = .95) and test-retest reliability is high (rre = .89, p < .001). Mainly all item reaction and discrimination indices fell within the optimal range. Confirmatory factor analysis resulted in the same four factors as in the original scale, except that the weights of factors 14, 8, 16, 24 of the items were slightly above the limit and the model fit indices were found to be slightly sub-optimal.

Conclusions. The instrument has very high internal consistency, adequate psychometric properties and high test-retest reliability. This Latvian adaptation of the SISRI-24 shows the closest alignment to the original version among all previous adaptations. Given that the test effectively measures a multifaceted concept and its items align with the intended factor structure, 4th version of SISRI-24 can be considered generally suitable for use in Latvia for measuring spiritual intelligence. Further in-depth studies of the test factor structure are desirable.
