The long process by which HTA became a paradigm: A longitudinal conceptual structure analysis.

This study maps the conceptual structure of health technology assessment (HTA) research with the aim of contributing to a better understanding of this research stream. A bibliometric analysis of 1,198 HTA articles retrieved from the Web of Science database was conducted. The analysis of descriptive performance indicators identified the main traits of the scientific debate about the HTA in terms of publications, productive countries, and sources.

Major depression and secondhand smoke exposure.

Background: Epidemiological studies have consistently linked smoking to poor mental health. Among non-smokers, some studies have also reported associations between secondhand smoke exposure and psychological symptoms. However, an association between secondhand smoke exposure and depressive disorders has not been well established.

The depression and marital status relationship is modified by both age and gender.

Background: Marital status is associated with major depression prevalence, however, the strength of association may be modified by age and gender.

Methods: The data sources were a series of cross sectional national health surveys of the Canadian population carried out by Statistics Canada during 1996-2013. These were cross-sectional files from the National Population Health Survey of 1996, together with the Canadian Community Health Surveys from 2000 to 2013; the respondents were 18 years and older.

Major depression and non-specific distress following smoking cessation in the Canadian general population.

Background: Outcome data from smoking cessation trials indicate that improvement in mental health occurs after smoking cessation. This suggests that smoking cessation should be a priority for mental health services. However, participants in such trials may not be representative of the general population.

A comparison of recommendations and received treatment for mood and anxiety disorders in a representative national sample.

Background: The exact nature of treatment and management recommendations made, and received, for mood and anxiety disorders in a community population is unclear. In addition, there is limited evidence on the impact of recommendations on actual receipt of treatment or implementation of management strategies. We aim to describe the frequency with which specific recommendations were made and implemented; and thus assess the size of any gap between the recommendation and implementation of treatments and management strategies.
