Table 3 The association between mental health variables and psychotropic drug use

⁶⁵Allard et al. (1995), n = 500

In bivariate analysis, drug use negatively correlated with morale (r = -0.32, p < 0.001)

⁶ Blazer et al. (2000), n = 4,162

In multivariate logistic regression, benzodiazepine use significantly associated with depressive symptoms at 10-year follow-up (OR: 2.13, p < 0.05)

⁶⁸ Dealberto et al. (1997), n = 2,812

In multivariate logistic regression, drug use significantly associated with depressive symptoms at 6-year follow-up (OR: 2.78, p < 0.001)

⁶⁹ Gustafsson et al. (1996), n = 421

In LISREL model, drug use positively correlated (0.63) with poor mental health (chi² = 3.38, p = 0.33)

⁹⁴ Paterniti et al. (1998), n = 1,389

In multivariate logistic regression, drug users 4 times more likely to report anxious and depressive symptoms than non-users (OR: 4.0, CI: 2.5–6.5)

⁶³ Gleason et al. (1998), n = 5,181

In multivariate logistic regression, benzodiazepine users 7 times more likely to report emotional or nervous problems than non-users (OR: 6.66, CI 5.1, 8.7)

⁷⁴ Taylor et al. (1998), n = 5,222

Depressive symptoms multiply by 3 the likelihood of using hypnotics and by 5.1 the likelihood of using anxiolytics. Anxious symptoms multiply by 4.2 the likelihood of using hypnotics and by 3 of using anxiolytics.
