Abstract
The casenotes of 144 doctors who had received treatment for substance misuse were analysed. There were no differences between general practitioners (h = 61) and hospital doctors (n = 58) in terms of their substance misuse histories or the problems they incurred. Differences emerged between the consultant (n = 24) and the non-consultant (n = 34) grades of hospital doctor. The consultants were older at onset of problematic use (42.6 ±8.6 vs. 29.9 ± 9.8 years); they suffered fewer career problems and misused fewer substances. The most frequent pathways into substance use were personality difficulties (76 subjects, 52.8%) and anxiety or depression (46 subjects, 31.9%). A history of depression (n = 36) was associated with perceived stress at work (p = 0.014), and at home (p = 0.06). Past neurotic disturbances (n = 20) were associated with personality difficulties (p = 0.035), anxiety or depression (p = 0.004), and with an earlier onset of problematic substance use (30.2 ± 8.3 vs. 36.5 ± 9.8 years, p = 0.014). Principal components of possible antecedents yielded one major component on which all elements loaded; this was labelled the ‘disturbance score’. This score showed a reduction with increasing age of onset of problematic substance use.
