Relationships between coping, anxiety, depression and health-related quality of life in outpatients with substance use disorders: results of the SUBUSQOL study.

Previous research showed that coping strategies are associated with depressive symptoms and health-related quality of life (HRQoL) in patients with chronic somatic conditions. The aim of this study was to examine the coping strategies used in patients with substance use disorders and to assess the relationships between coping strategies, HRQoL, anxiety and depression. Coping was assessed in a prospective outpatient cohort by the Brief COPE. Additionally, sociodemographic and clinical data were collected, and questionnaires assessing HRQoL (SF-12) and states of anxiety and depression were completed. Cross-sectional analysis using Pearson correlations and multiple linear regression was performed. A total of 244 patients were included. Acceptance, planning and self-blame were the most used coping strategies. Strong correlations were found between anxiety, depression, coping strategies and HRQoL. On the MCS-12, better scores were associated with male gender, lack of anxiety or depression and coping styles based on less self-blame, on positive reframing, acceptance, and behavioral disengagement. Patients without depression or anxiety, and no comorbidity had better scores on the SF-12 PCS. Coping strategies of substance-dependent outpatients should be assessed, as they might be useful for identifying patients in need of support. Furthermore, interventions that improve coping capabilities might be helpful for improving HRQoL.

Factors involved in seeking care at a specialty service among alcoholic rural French women: A cross-sectional study of rural women.

BACKGROUND: Few studies of mental health or substance abuse have focused on rural life. This study aimed to evaluate the association between socio-demographic and clinical characteristics and the probability of rural alcoholic women seeking help on their own at a specialty treatment service. METHODS: This exploratory study used a cross-sectional design to collect data from alcoholic women upon admission to a French outpatient department. Multiple logistic regression models tested whether the socio-demographic and clinical characteristics of these women predicted the likelihood that they would seek treatment at a specialty service on their own. RESULTS: Among 50 rural alcoholic women, the probability of seeking help on their own at a specialty treatment service was 5.6 times greater (95% CI 1.2-25.7, P=0.03) for participants with a history of physical and/or sexual trauma and 5.1 times greater (95% CI 1.1-24, P=0.03) among women with no complementary health insurance. CONCLUSION: Increased knowledge of the specific characteristics of rural alcoholic women is needed to develop programs that will increase awareness of and access to specialty treatment services among these women.

The effects of patient and physician characteristics on early outpatient satisfaction with substance dependence care: results of the SUBUSQOL study.

BACKGROUND: Although patient perceptions of health care have increasingly been explored in the literature, little is known about care satisfaction among individuals with substance dependence. This exploratory study assessed the relationships between patient and physician characteristics and early outpatient satisfaction with care for alcohol and opioid dependence. METHODS: Satisfaction was assessed using a multidimensional, self-administered and validated questionnaire during the early care process among a prospective outpatient cohort. In addition to measuring satisfaction and obtaining sociodemographic and clinical data, this study collected data on the self-reported health status and physician characteristics at inclusion. Cross-sectional analysis with multiple linear regression was performed to identify the variables associated with satisfaction level. RESULTS: A total of 249 outpatients were included, and 63.8% completed the satisfaction questionnaire. Patients without a history of previous care for substance dependence were more satisfied with the appointment-making process (ß=7.2; P=0.029) and with the doctor consultation (ß=10.3; P=0.003) than those who had received care previously. Neither sociodemographic characteristics nor self-reported health status was associated with outpatient satisfaction. CONCLUSION: The factors that affect patients' ratings of early satisfaction with the care that they receive should be studied further because increased understanding of the factors that negatively affect these ratings might enable caregivers and outpatient management facilities to improve the patient experience during the early stages of care, which might in turn improve treatment adherence, continuity of care, and other health-related outcomes.

Differential item functioning (DIF) of SF-12 and Q-LES-Q-SF items among french substance users.

BACKGROUND: Differential Item Functioning (DIF) is investigated to ensure that each item displays a consistent pattern of responses irrespective of the characteristics of the respondents. Assessing DIF helps to understand the nature of instruments, to assess the quality of a measure and to interpret results. This study aimed to examine whether the items of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) and Short-Form 12 (SF-12) exhibit DIF. METHOD: A total of 124 outpatients diagnosed with substance dependence participated in a cross-sectional, multicenter study. In addition to the Q-LES-Q-SF and SF-12 results, demographic data such as age, sex, type of substance dependence and education level were collected. Rasch analysis was conducted (using RUMM2020 software) to assess DIF of the Q-LES-Q-SF and SF-12 items. RESULTS: For SF-12, significant age-related uniform DIF was found in two of the 12 items, and sex-related DIF was found in one of the 12 items. All of the observed DIF effects in SF-12 were found among the mental health items. Three items showed DIF on the Q-LES-Q-SF; however, the impact of DIF item on the delta score calculation for the comparisons of self-reported health status between the groups was minimal in the SF-12 and small in the Q-LES-Q-SF. CONCLUSION: These results indicated that no major measurement bias affects the validity of the self-reported health status assessed using the Q-LES-Q-SF or SF-12. Thus, these questionnaires are largely robust measures of self-reported health status among substance users.

Combination of classical test theory (CTT) and item response theory (IRT) analysis to study the psychometric properties of the French version of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF).

OBJECTIVE: The study aimed to examine the construct validity and reliability of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) according to both classical test and item response theories. METHOD: The psychometric properties of the French version of this instrument were investigated in a cross-sectional, multicenter study. A total of 124 outpatients with a substance dependence diagnosis participated in the study. Psychometric evaluation included descriptive analysis, internal consistency, test-retest reliability, and validity. The dimensionality of the instrument was explored using a combination of the classical test, confirmatory factor analysis (CFA), and an item response theory analysis, the Person Separation Index (PSI), in a complementary manner. RESULTS: The results of the Q-LES-Q-SF revealed that the questionnaire was easy to administer and the acceptability was good. The internal consistency and the test-retest reliability were 0.9 and 0.88, respectively. All items were significantly correlated with the total score and the SF-12 used in the study. The CFA with one factor model was good, and for the unidimensional construct, the PSI was found to be 0.902. CONCLUSION: The French version of the Q-LES-Q-SF yielded valid and reliable clinical assessments of the quality of life for future research and clinical practice involving French substance abusers. In response to recent questioning regarding the unidimensionality or bidimensionality of the instrument and according to the underlying theoretical unidimensional construct used for its development, this study suggests the Q-LES-Q-SF as a one-dimension questionnaire in French QoL studies.
