Cognitive-behavioral counseling and self-perception of male clients receiving methadone maintenance treatment

Validation of Texas Christian University Psychosocial Functioning and Motivation Scales in Iranian Persons Who Use Drugs

BACKGROUND

The psychosocial functioning and motivation scales of the Texas Cristian University (TCU) were translated and validated for the Persons Who Use Drugs (PWUDs).

METHODS

This study was carried out as a methodological research. The scales were translated forward and backward and then, the PWUDs in Kermanshah-based (west of Iran) substance abuse treatment centers in 2019 filled out the scales. Participants included 250 individuals who were selected by convenience sampling method. A demographics form and psychosocial functioning and motivation scales were used to collect data. For data analysis, content validity, face validity, testretest, internal consistency, and construct validity were applied by using exploratory analysis methods in SPSS (v.20) and confirmatory factor analysis in LISREL software.

RESULTS

Exploratory Factor Analysis (EFA) results were obtained by using the main component analysis and Varimax rotation of three factors (psychological function, social function, treatment motivation). Extracted factors, along with the eigenvalues, attributed variance percentage, and cumulative attributed variances by each factor, by 68.56%, showed a total variance of the questionnaire. Moreover, the fitness indexes of the Confirmatory Factor Analysis (CFA) of psychological function, social function, and treatment motivation were 0.059, 0.075 and 0.072, respectively. Therefore, the questionnaire fitness was at an acceptable level. The test-retest reliability coefficient was 0.875, and the Cronbachs alpha coefficient for all the components was higher than 0.71.

CONCLUSION

The results showed that psychosocial functioning, motivation scales have good psychometric properties, and they can be used in research and treatment fields.

Validation and psychometric properties of the community assessment inventory in Iranian persons who use drug

Objective

Social support is a key factor in the treatment and rehabilitation process of persons who use drug (PWUD). This highlights the need for a valid and reliable tool for assessing social support. The cultural and psychometric properties of community assessment inventory (CAI) in PWUDs under methadone therapy were examined in Iran in 2019.

Methods

The study was carried out as a validation and methodological study. At first, the original tool was translated into Farsi using forward-backward method. After ensuring face validity and content validity, construct reliability of the tool was supported using explorative and confirmatory factor analysis (EFA & CFA) using a sample group of 392 participants. The participants were selected through convenient-quota sampling from 24 drug clinics. Reliability of the questionnaire was supported using Pearson correlation coefficient and internal consistency based on Cronbach’s alpha.

Results

To determine content validity of the tool, CVI and CVR of it were obtained, which were on average equal to 0.79 and 0.59 respectively. The EFA supported correlation of the 37itmes of the tool (KMO = 0.975, Chi-square = 15,051.6, P_value=0.0001). The main indices of the model, based on CFA were higher than 0.9, which support goodness of fit of the model (χ2/DF = 2.98, CFI = 0.91, NFI, TLI = 0.905 GF = 0.92, REMSEA = 0.07, R2 = 0.99). Reliability of the tool based on internal consistency (Cronbach’s alpha) for the subscales were in 0.8–0.95 interval and equal to 0.85 for the whole tool.

Conclusion

As the results showed, CAI had acceptable indices for Iranian PWUDs under methadone therapy. The tool can be used for assessing social support level in the study population. It is a reliable and valid tool for studies in pertinent fields.
