Psychometric Properties of the Spanish Version of the Changes in Sexual Functioning Questionnaire-Short-Form (CSFQ-14) in a Sample of Males with Drug Abuse History

Adaptation and Validation of the Sexual Assertiveness Scale (SAS) in a Sample of Male Drug Users

The aim of the present study was to adapt and validate the Sexual Assertiveness Scale (SAS) in a sample of male drug users. A sample of 326 male drug users and 322 non-clinical males was selected by cluster sampling and convenience sampling, respectively. Results showed that the scale had good psychometric properties and adequate internal consistency reliability (Initiation = .66, Refusal = .74 and STD-P = .79). An evaluation of the invariance showed strong factor equivalence between both samples. A high and moderate effect of Differential Item Functioning was only found in items 1 and 14 (∆R 2 Nagelkerke = .076 and .037, respectively). We strongly recommend not using item 1 if the goal is to compare the scores of both groups, otherwise the comparison will be biased. Correlations obtained between the CSFQ-14 and the safe sex ratio and the SAS subscales were significant (CI = 95%) and indicated good concurrent validity. Scores of male drug users were similar to those of non-clinical males. Therefore, the adaptation of the SAS to drug users provides enough guarantees for reliable and valid use in both clinical practice and research, although care should be taken with item 1.

Adaptation, equivalence, and validation of the changes in sexual functioning questionnaire-drugs in a sample of drug-dependent men

This study aimed to adapt and validate the changes in sexual functioning questionnaire-short form in a sample of drug-dependent men, achieving equivalence. Participants were 301 drug-dependent and 202 non-drug-dependent men took part in this study. The analysis of invariance revealed strong factor equivalence (RMSEA = .06; χ2/df = 2.66 and ΔCFI = -.01) for the 4-factor model (desire, pleasure, arousal, and orgasm). This model has shown the best fit indices. No items showed differential item functioning (ΔR (2) Nagelkerke < .035). Reliability ranged from α = 0.83 for pleasure to α = 0.61 for orgasm. A comparison between the scores of control and experimental participants showed significant differences (CI = 99%) in all the dimensions. Thus, a worse sexual functioning has been observed in the drug consumer group. The adaptation of the Changes in Sexual Functioning Questionnaire-short form to drug-dependent individuals showed good psychometric properties.

Effect of drug use and influence of abstinence on sexual functioning in a Spanish male drug-dependent sample: a multisite study

INTRODUCTION

To date, it has been difficult to address the issue of sexual functioning and drug use, and many approaches to it have basic problems and methodological errors.

AIM

The present cross-sectional study compared the sexual functioning scores of a group of drug users with those of a group of nondrug users. It explored the relationship between drug abstinence and sexual functioning.

MAIN OUTCOME MEASURES

A sample of 905 males participated in this study (549 met the substance dependence criteria and 356 were controls). All of them were assessed with the Changes in Sexual Functioning Questionnaire-Drugs version.

METHOD

The assessment was conducted from September 2009 to January 2011. The clinical sample was evaluated in nine different substance abuse treatment facilities.

RESULTS

Results show that, overall, all dimensions (pleasure, desire, arousal, and orgasm) were moderately impaired. Yet, differences regarding preferred substance were observed. Pleasure and orgasm were the two areas most significantly impaired. In these areas, all drugs seemed to negatively affect sexual functioning. However, desire and arousal were not affected by all the substances. In addition, at least after 2 weeks of drug abstinence, no relationship was found between drug abstinence and improvement in sexual functioning. The sample studied had an average of 1 year of drug abstinence and was found to have poorer sexual functioning than the control group.

CONCLUSIONS

Therefore, these results seem to contradict those that argue that drug use only impairs sexual functioning temporarily. Moreover, they suggest that sexual functioning does not improve just by stopping drug use.

[Validation of Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) in a Spanish population]

OBJECTIVE

Due to the lack of psychometric studies using the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) in Spain, its Spanish validation is proposed in the present study, by analysing its reliability and validity.

DESIGN

Cross-sectional descriptive study.

SETTING

General population. Conducted in 20 provinces.

PARTICIPANTS

The sample consisted of 3,050 participants (45.41% men and 54.59% women) and was selected using a quota convenience sampling procedure. They ranged in age from 18 to 83 years-old (M=41.51; SD=13.45).

MAIN MEASUREMENTS

Spanish versions of the MGH-SFQ, Sexual Assertiveness Scale, Sexual Desire Inventory, and Index of Sexual Satisfaction.

RESULTS

The MGH-SFQ showed a single dimensional structure, which explained 71.35% of variance in men and 83.56% in women. Reliability values were .90 and .93, respectively. Convergent validity was adequate as their scores were positively correlated to initiation sexual assertiveness, dyadic sexual desire, and sexual satisfaction. The MGH-SFQ identified that females showed more sexual dysfunctions than males, and detected more sexual dysfunctions as age increases.

CONCLUSIONS

The Spanish validation of the MGH-SFQ is a reliable and valid self-reporting questionnaire to assess sexual dysfunctions in Spain. Its psychometric goodness of fit, together with its brevity and ease of use, make it a useful instrument to detect overall, as well as particular sexual dysfunctions.
