Q

Main Points

A

very high prevalence of lifetime disorder (48%).
trade-off in gender patterns
“Co-morbidity” makes this possible.
For depression, anxiety, alcohol – each experienced by at least 1 in 5 (20%).

Q

The NCS – R (Replication) - 2005

A

Concordance of diagnoses between the CIDI for the DSM-IV and blind separate clinical assessments much higher than in previous studies — a good thing..

The NCS – R (Replication) - 2005

A

NCS had emphasized early onset between ages 18-25.

approximation probes between major life markers + more precise wording – “do you remember the exact age..?”

Q

Age of Onset

A

first onset of major mental disorders occurred during the adult transition (18-24).
Results here are different, in part because of the new ways of asking about it.

Consistent Differences (U.S.)
Marital status still protective, despite its reputation.. Education categories emphasize the complexity of level vs. discontinuity. Income as a measure of SES may be more consistent.

Prevalence in Toronto 1991
Pattern quite similar to the original NCS. | Rates not significantly lower

Social Patterns in Toronto 1991
Odds ratios relative to a reference group: | Females had 1.6 times the chance relative to males of having a depression or anxiety disorder.

Social Patterns of Distress: Same or Different as Disorder?
six established social patterns of distress, and they do largely mirror the patterns for mood and anxiety disorder.
31
Social Patterns of Distress: Same or Different as Disorder?
Females higher rates of distress Married less distressed. SES inversely related to distress.
32
Social Patterns of Distress: Same or Different as Disorder?
Parents with children at home more distressed (unique) | Undesirable life changes (stressors) related to distress (the effect of social stress)
33
Social Patterns of Distress: Same or Different as Disorder?
Age is curvilinear, with middle-aged people the least depressed, older people the least anxious (unique)
34
Others Not Considered Here
``` Williams on race: higher on distress, lower on risk of disorder Chronic stressors (strongly) related to distress. ```
35
Others Not Considered Here
Note: in explaining SES, M and R suggest: daily grind-the problems that are always there-wear at the nerves and demoralize the spirit. Some people have many problems and fewer resources to solve them. Childhood traumas related to distress later in life.
36
Others Not Considered Here
Areas of uncertainty, inconsistency: Race / Ethnicity Nativity (country of birth) Religion
37
The World According to M and R:SES
Extremes of SES differences greater than differences due to gender or marital status.. May be combined effect of chronic stress PLUS fewer resources (sense of control)
38
The World According to M and R:SES
Income matters more at lower levels | Education levels gender difference
39
The World According to M and R:Marriage
Marriage still works --- beyond the studies cited | Why?
40
The World According to M and R:Marriage
Social capital functions Stable social support Secure form of relationship
41
The World According to M and R:Marriage
Structured common fate Works as an identity signal; a status characteristic Better relationships Economic multiplier.
42
The World According to M and R:Children
Treated as if they nullify the effect of marriage Part of the effect is to increase overall demands across roles; part is the effect of stress proliferation on finances and in the marriage , as in…
43
The World According to M and R:Children
Before / during / after children an important issue --- there is a difference between before and after.
44
The World According to M and R:Gender
Need to carry forward much of this discussion to next week, and focus on the specificities and conditions of gender differences.
45
The World According to M and R:Gender
Historical change – from role underload to role overload; essentially opposite arguments. Gender differences as a methods artifact vs. a “real” difference: Can’t have both – they are in tension.
46
The World According to M and R:Age
Depression curvilinear with a minimum in mid-life -- is this still the case? (cohort an issue…)
47
The World According to M and R:Age
Recent studies sometimes suggest no / less upturn in later life. Anxiety and anger do not follow this pattern…. Tend to decline in later life.

Wheaton and Hall (1996): social Patterns of distress in Canada in NPHS
females have higher distress SES inversely age has negative effect both never and prev have negative effects

Turner and Lloyd (1999): Patterns in Toronto
Longitudinal (minimally). Similar findings. Findings for gender, age and SES very similar, but marital status less so.

Social Class (Eaton et al in text)
``` core importance of stratification + core role of social class in stratification Stratification df: “process by which individuals accorded unequal access to rewards and resources in society.” ```
52
Social Class (Eaton et al in text)
Social Class df: “groups of indivs who are similar in their wealth, power, and prestige + 1) interact with one another more often than randomly, 2) are aware of a set of common interests
53
Social Class (Eaton et al in text)
Measures: Income (household) Education (years, levels, or degrees) Occupational Status or Prestige (scale score for occupations)
54
The Causes of Inequality
Is stratification endemic and universal? Functionalist position: occupational reward system demands differential rewards and prestige for more demanding, high skill occupations.
55
The Causes of Inequality
A “natural” state Conflict position: Power begets protection of resources and reward system; conflict of interests a natural product. Not an equilibrium
56
Social Causation, Social Selection and Timing: A Fundamental Issue
Eaton points out the crucial role of adolescence in the unfolding future relationship between social class and mental health.
57
Social Causation, Social Selection and Timing: A Fundamental Issue
Importance of late adolescence / early adulthood: | negotiation between current social class, mental health, and future social class
58
Social Causation, Social Selection and Timing: A Fundamental Issue
educational choices and performance are “finalized” in this period age of first onset of many disorders
59
Social Causation, Social Selection and Timing: A Fundamental Issue
whether social causation or social selection predominates may depend on this stage of life (see #1). first job after education is crucially important to the rest of one’s work career.
60
Social Causation
the argument that social position (status) has a causal role in the production of disorder.
61
Social Selection
the opposite argument: Disorder, usually biologically caused, leads to problems in functioning and thus loss in status and social position over time.
62
Selection vs. Causation
more general version of causation vs. selection: substitute “social environment and experience” for “social position

Social Class: The History
``` Jarvis report (1855) on “lunacy” and poverty, based on medical and clergical reports, and local leaders in towns. Chances for opportunistic labeling clear. ```
69
Social Class: The History
``` Still, reports that the rate of lunacy per 1,000 population was 65/1000 in the “pauper” class, and only 1/1000 in the “independent” class. The first known attempt to relate class to mental health. ```

Social Class and Disorder
Lorant et al meta-analysis…careful! | Overall odds of lowest SES relative to highest SES in prevalence studies: 1.81
72
Social Class and Disorder
Overall odds of lowest SES to highest SES in incidence studies: 1.24 Both significant, but the difference means something. Incidence follows non-cases and relates the risk of becoming a case to past SES.
73
Social Class and Disorder
Difference indicates --- Some causal role for SES but also some selection. SES affects persistence of disorder as well.

Early Examples: Social Class and Stress
``` The question is….: Is lower social class that closely related to the rate of occurrence of stressful life events, as opposed to more chronic stressful life condtions? whether many of the stressful life changes measured in major studies are patterned or random….. ```
84
Items on the Stressful Life Event Scale: How Many are Random?
too many answers
85
Social Class and Coping Resources: Fatalism
The Model: Low SES undermines the development of a belief in control over life outcomes – thus, higher fatalism. Higher fatalism increases risk of disorder due to lack of persistence and effort in coping situations. No need to theorize greater stress at low SES.
