High unemployment rates in many developing countries have prompted research to focus on sustainability and inclusiveness of employment in line with the sustainable development goal target 8.6. The democratic republic of Congo (DRC) in sub-Saharan Africa experiences one of the highest youth unemployment rates owing to its long-term socio-political and economic instability. Qualitative and quantitative research studies have linked low employability of university-educated youth in the DRC to tribalism, corruption, and insecurity. The current study sought to identify contextual factors that predict employability of information technology (IT) graduates in the DRC. The study surveyed 355 graduates (274 male, 81 female) using 43 questionnaire. Bartlett test was 3,930.05 for Chi2 ( p-value = .000) and KMO test scored 0.68. McDonald’s Omega test of reliability of the instrument scored 0.77 with a total cumulative variance of 72.02%. Results of this study advance the conflict theory by pinpointing the true factors which influence the employability of IT graduates in unstable developing countries. This study has discovered that socio-political background of graduates, graduate academic competencies, graduate-employer relationship, and university employability strategies are the contextual factors that predict the employability of IT graduates in the DRC. The Cronbach’s Alpha test of reliability for the retained contextual factors scored .78, .75, .63, and .53, respectively.

“…The determinant score was 0.00003077 indicating that an absence of multicollinearity in the data, which made it be suitable for factor analysis [ 53 ]. The Kaiser–Meyer–Olkin value (0.84) indicated that the adequate sampling; the approximate chi-square of the Bartlett’s test of Sphericity of the total scale was 2671.69 with the degrees of freedom ratio 528 (p < 0.001) showed that the data set was worth for a factor analysis [ 37 ].…”

Background The Traditional Chinese Medicine (TCM) Body Constitution Questionnaire (For Elderly People) (TCMECQ) is a patient-reported outcome questionnaire developed in Mandarin in 2013 to differentiate the body constitutions of the elderly aged 65 and above. Considering the cultural and linguistic differences between Mainland China and Hong Kong (HK) Special Administrative Region, the TCMECQ was translated into Cantonese following “back translation” policy and validated in proper process. Methods Ten Chinese Medicine Practitioners (CMPs) and 30 senior citizens aged 65 or above were recruited to evaluate the first version of the Traditional Chinese Medicine Body Constitution Questionnaire (For Elderly People) (Cantonese version) (TCMECQ-C). Based on their comments, the second version was developed and discussed in the panel meeting to form the third version, validated the third version on 270 recruited seniors. Based on the validation results, a panel of 5 experts finalized the Questionnaire as the final version. The TCMECQ-C developers finalized the Questionnaire as the validated endorsed third version (i.e. final version). Results The item-level content validity index of most items of the TCMECQ-C (First Version) were ranging from 0.80 to 1.00 in terms of clarity, relevance and appropriateness. Factor loadings of Qi-deficiency Constitution ranging from 0.37 to 0.71, Yang-deficiency Constitution ranging from 0.36 to 0.65, Yin-deficiency Constitution ranging from 0.36 to 0.65, and Stagnant Qi Constitution ranging from 0.68 to 0.82. The chi-squared degree-of-freedom ratio was 2.13 (928.63/436), Goodness-of-Fit Index (0.83), Adjusted Goodness-of-Fit Index (0.79), Normed Fit Index (0.66), Comparative Fit Index (0.78), Incremental Fit Index (0.78), Relative Fit Index (0.61) and Tucker–Lewis Index (0.75), and Root Mean Square Error of Approximation (0.07) and Standardized Root Mean Square Residual (0.07), implied acceptable Confirmatory Factor Analysis model fit of the overall scale. A Pearson correlation coefficient (r) showed the sufficient convergent validity for excessive subscales (Phlegm-dampness Constitution and Dampness-heat Constitution with r = 0.35, p < 0.01). Cronbach’s alpha coefficient ranged from 0.56 to 0.89, including Qi-deficiency Constitution (0.67), Yang-deficiency Constitution (0.84), Yin-deficiency Constitution (0.59), Stagnant Blood Constitution (0.56), Stagnant Qi Constitution (0.89), Inherited Special Constitution (0.76) and Balanced Constitution (0.73), indicating acceptable internal consistency for subscales. The intra-class correlation coefficients of the TCMECQ-C ranged from 0.70 to 0.87 (p < 0.001), indicating moderate to good test–retest reliability. Conclusion TCMECQ-C is a valid and reliable questionnaire for assessing the body constitution in Cantonese elderly.
