Assessing the dimensionality of the sense of coherence scale (SOC-L9) using Ghanaian university students: Guarding against the method effect

Background

The dimensionality of the sense of coherence (SOC-L9) scale has been in contention due to the varied factor structure revealed in the literature. In this study, we assessed the dimensionality of the SOC-L9 scale using Ghanaian university students while guarding against the method effect. The study also examined the gender measurement invariance of the scale.

Methods

This research conveniently sampled 1062 students who responded to the SOC-L9 scale with negative items reversed to positive items. A larger proportion of the participants were male students (n = 769, 72.4 %), with 293(27.6 %) being female students. The youngest participant was 18 years old, whereas the oldest was 42 years old. Following all validation studies protocols, four distinct confirmatory factor analysis models were fitted and compared (i.e., unidimensional, three-factor first-order, three-factor second-order and bifactor models).

Results

The initial model comparison revealed that the bifactor CFA model [CFI = 0.958, SRMR = 0.036, AIC = 21231.35, BIC = 21370.45] was superior to the unidimensional [CFI = 0.914, SRMR = 0.046, AIC = 26280.67, BIC = 26414.8] and 3-factor models [CFI = 0.932, SRMR = 0.040, AIC = 26221.67, BIC = 26370.71]. Upon further probing, it was discovered that SOC-L9 functions best as a unidimensional scale for the university student population. Gender measurement invariance was established for configural invariance [CFI = 0.986, SRMR = 0.044], metric invariance [CFI = 0.894, SRMR = 0.051] and scalar invariance [CFI = 0.983, SRMR = 0.047].

Conclusion

The SOC-L9 scale has a nested structure with the various sub-scales interacting to produce a summary total observed score. The structure of the SOC-L9 requires scholars to treat the scale as a unidimensional scale rather than a multidimensional one. This latent structure was found to be consistent with male and female university students.

Examining the underlying latent structure of the sports emotion questionnaire: Insights from the bifactor multidimensional item response theory

Background

Despite the widespread use of the sports emotion questionnaire (SEQ) in several studies, it is surprising that only a few have explicitly tested the validity and utility of the instrument in non-western populations. Besides, the issue of dimensionality and the latent structure of the instrument remain inconclusive given that several authors have revealed different factor structures across diverse populations. The central concern is whether the items on the various dimensions, proposed for the original SEQ, offer adequate information to their respective expected subscale or otherwise. This study assessed the underlying latent structure of the SEQ using confirmatory and bifactor multidimensional item response (MIRT) models.

Methods

Through a well-designed validation study 300 athletes from three West African countries, participating in the 2018 West African University Games were surveyed to respond to the SEQ. The data were analyzed using first, a 5-factor confirmatory factor analysis (CFA) via the MIRT model and second, a bifactor MIRT analysis.

Results

The results revealed that items on the SEQ were fairly good in measuring the construct under the respective domains of the instrument. However, the outcome of the bifactor model showed that the majority of the items on the SEQ explained common variance in relation to the general factor other than the specific domains (5-dimensions).

Conclusion

Findings of the bifactor model question whether the sub-dimensions of the SEQ are needed since most of the items on the SEQ explained larger variances in the general factor than any of the five domains. It is concluded that instruments like SEQ should be scored for a general factor and not as sub-dimensions. Further investigations are encouraged by scholars within the area to probe the dimensionality of the SEQ.
