Validation of the Waterpipe Tolerance Questionnaire Among Jordanian School-Going Adolescent Waterpipe Users

Perceived stress and willingness to quit smoking among patients with depressive and anxiety disorders seeking treatment

Rationale and objectives

Little are known about nicotine dependence (ND), perceived stress, and willingness to quit smoking at different treatment stages in patient with affective disorders (AD). This study aimed to evaluate the association between ND and perceived stress among patients with AD presenting with psychiatric treatment at different clinical stages (first visit or follow‐up), and in different nicotine type users (cigarette and waterpipe smokers). We also aimed to evaluate the willingness to quit smoking and its association with barriers to quitting.

Methods

This cross‐sectional mixed‐method study collected quantitative and qualitative data from patients (n = 57) presenting for treatment with AD and ND at different sites in Saudi Arabia. Quantitative validated scales were used to assess the 70 of depression symptoms, anxiety symptoms, perceived stress, and ND. Qualitative questions assessed barriers to quit smoking. We used a linear regression modeling to estimate the association between ND and perceived stress as well as to estimate the association between barrier to quit and willingness to quit.

Results

ND had a statistically significant association with perceived stress (odds ratio [OR]: 2.09; 95% confidence interval [CI]: 1.20‐3.63). Participants in the follow‐up group had a higher ND score than those in the first‐visit group. One of the most commonly reported barriers to quitting was using nicotine as a stress management (33.3%), which predicted positive willingness to quit (OR: 2.23; 95% CI: 1.48‐3.37; P < .01). Boredom was reported as a barrier in the waterpipe group more than cigarette group.

Conclusion

ND has a significant association with perceived stress regardless of treatment status in patients with AD, indicating the need to evaluate smoking cessation during the early stages of treatment for patients with AD and ND. It will be critical for clinicians to offer patients with AD alternative coping mechanisms to manage stress and boredom.

Lebanese Waterpipe Dependence Scale (LWDS-11) validation in a sample of Lebanese adolescents

Background

Salameh et al. developed the Lebanese Waterpipe Dependence Scale (LWDS-11) that assesses nicotine dependence among adult waterpipe smokers. In view of the high waterpipe use among Lebanese youth and other neighboring countries, it was deemed necessary to check the psychometric properties of the LWDS-11, originally adapted to the Lebanese population, to measure nicotine dependence among adolescents.

Methods

Two cross-sectional investigations were conducted; Study 1 (January and May 2019) enrolled a total of 449 students who were exclusive waterpipe smokers; this sample was used to conduct the exploratory factor analysis. Study 2 enrolled another sample composed of 243 waterpipe smoking adolescents. This sample was independent from the first one and was used to conduct the confirmatory analysis.

Results

The results also showed that 312 (69.5%) [95% CI 0.652–0.738] had high waterpipe dependence (scores of ≥10). Results of the factor analysis in sample 1 showed that all LWDS-11 items were extracted following the factor analysis. Items converged over a solution of one factor; total variance explained = 70.45%, α_Cronbach = 0.96). The results of the confirmatory factor analysis were as follows: the Maximum Likelihood Chi-Square = 129.58 and Degrees of Freedom = 45, which gave a χ²/df = 2.88. For non-centrality fit indices, the Steiger-Lind Root Mean Square Error of Approximation (RMSEA) was 0.08 [0.071–0.106]. Moreover, the Comparative Fit Index (CFI) value was 0.77.

Conclusion

The preliminary results suggest that the LWDS-11 has good psychometric properties to measure waterpipe dependence among adolescents. We hope this tool would serve the benefit of research and epidemiology.

The Syrian Center for Tobacco Studies-13 (SCTS-13): Psychometric evaluation of a waterpipe-specific nicotine dependence instrument

BACKGROUND

Waterpipe tobacco smoking (WTS) has surged globally among young people and causes nicotine dependence (ND). No existing ND instruments are sensitive to waterpipe-specific features of ND and early stages of use.

METHODS

We conducted a psychometric scale evaluation among 192 current waterpipe smokers, initially averaging 15 years of age, recruited from schools in Beirut, Lebanon, and assessed 4 times, 6 months apart. Twenty eight self-report items tapping multiple features of ND were submitted to exploratory and confirmatory factor analyses (EFA and CFA) to reduce items and verify factor structure. Convergent validity was assessed with the Lebanese Waterpipe Dependence Scale and the Hooked on Nicotine Checklist, and discriminant validity with the Depressive Symptom Scale and Adolescent Life Events Stress Scale. Concurrent and predictive validity measures included smoking status and intensity (amount, frequency, session duration, and change in frequency), quitting interest and success, perceived addiction, and smoking alone.

RESULTS

The EFA yielded a single factor, 13 item solution (named the Syrian Center for Tobacco Studies [SCTS]-13) that explained 91% of variance in responses, was internally consistent (Cronbach's alpha and McDonald's omega = 0.87), and captured several positive reinforcement, negative reinforcement, and social/sensory-related features of ND. The CFA indicated good model fit. The SCTS-13 showed acceptable convergent and discriminant validity. Higher SCTS-13 scores predicted current waterpipe and dual (waterpipe and cigarette) smoking, greater intensity of use, less interest in quitting, shorter duration of abstinence, greater perceived addiction, and smoking alone (vs. socially).

CONCLUSION

The SCTS-13 is a promising brief, waterpipe-specific ND instrument.

Now is the time to advocate for interventions designed specifically to prevent and control waterpipe tobacco smoking

Waterpipe tobacco usage is spreading rapidly worldwide, with reports of more youth being waterpipe users compared to adults. In many areas of the world, waterpipe usage surpasses cigarette smoking. Waterpipes and cigarettes are both mechanisms for inhalation of tobacco smoke and therefore have serious health consequences. However, because of the many differences between the two products, prevention and control strategies that have proven effective for cigarettes may not transfer readily to waterpipe. This report highlights the differences between waterpipes and cigarettes in toxicant exposure and physiologic effects, patterns of use, social norms, the extent of evidence, and the policy environment. There is little evidence to date around effective interventions for waterpipe prevention and control. The current state of evidence for intervention to curb or control waterpipe is at ground zero and critically needs attention from both scientists and policy makers. National and global efforts aimed at cigarette prevention have succeeded, particularly in developed countries. We suggest the time has come to harness what we know works for cigarette prevention and control and adapt it to tackle the growing epidemic of waterpipe tobacco use.
