Studies have found that the lower the socioeconomic status (SES) of an individual, the higher his or her risk of mental illness. Research conducted in communities reported that regardless of the type of SES indicator used—whether education, income, or occupation—or the type of mental illness examined, similar associations were observed. Several large-scale population studies were administered to study such patterns across the US.
Using the National Comorbidity Study (NCS), a large study of psychiatric disorder in the US, researchers looked at the relationship between education attainment and income levels (Study 1). The survey interviewed over 8,000 people ages 15-54 and was the first to use a national probability sample to estimate psychiatric disorders. The psychiatric disorders assessed in the NCS include major depression, mania, dysthymia, panic disorder, social phobia, nonaffective psychosis (psychosis not related to moods or emotions), etc. Table 1 below shows the odds ratios for the levels of broad categories of psychiatric disorders by educational level (years) and income level. The results indicate bivariate associations. The value of 1.00 in the last columns of education and income indicate that the highest levels serve as the reference category. An odds ratio greater than 1.0 indicates a higher prevalence of that disorder for those in the specified category relative to those in the reference category. For example, the value 2.33 for “any disorder” indicates that people with 0-11 years of education are 2.33 times more likely to experience any disorder compared to those in the reference group (16+ years of education).
Table 1: Odds ratios for psychiatric disorders (in the last 12 months) by years of education and annual income, National Comorbidity Study (n=8,098).
While the above study asserts that conditions of life associated with low SES increase risks of mental disorders, other researchers conducted a study which found that existing mental illnesses actually impairs status and educational attainment (Study 2). For example, they found that mental disorders may cause downward movement among adults and lead them to “drift” into the lower socioeconomic strata.

[question] => According to the results on the relationship between educational attainment and psychiatric disorders in Table 1, which of the following is true?
[value] => Array
(
[answer] => 4
[description] => Reason for the Correct Answer:
College educational level is the baseline group.
Each educational attainment category is compared with the baseline (reference) group.
Compared to those who have completed college education or more, those who did not complete a high school degree (12 years) are 1.79 times more likely to be diagnosed with major affective disorders.

[each_answer] => A. Among those with completed high school education, substance abuse/dependence disorder is only 0.10 times more likely to be the diagnosis than anxiety disorder.

[question] => Based on the results reported in Table 1, which of the following is NOT true regarding the association between income level and psychiatric disorders?
[value] => Array
(
[answer] => 1
[description] => Reason for the Correct Answer:
The highest income level (70K+) is the baseline (reference group).
Each income category is compared to the highest income group.
The higher the income, the less likely an individual will have psychiatric disorders.
The lowest income group is 3.36 times more likely to have three or more disorders compared to the highest income category, not those earning 20-34K.

[question] => In Study 2, researchers described how mental disorders may cause downward movement among adults and lead them to “drift” into the lower socioeconomic strata. Which sociological concept best illustrates this “drift”?
[value] => Array
(
[answer] => 2
[description] => Reason for the Correct Answer:
This concept demonstrates changes or movement in individuals’ social status.
This concept is defined as movement of individuals, families, households, or other categories of people within or between layers or tiers in an open system of social stratification.
Social mobility demonstrates the drift or movement from one social strata to another. Social mobility can be upward and downward mobility.

[question] => In Study 2, researchers refuted how education and income level contributed to increased risks of psychiatric disorders. Instead, they argue that the presence of mental disorders impairs an individual’s social status. Which of the following is correct regarding the research design of Study 2?
[value] => Array
(
[answer] => 4
[description] => Reason for the Correct Answer:
In Study 2, researchers examine the impact of mental disorders on social status outcomes.
The presence or nonpresence of mental disorders has an effect on social status outcomes.
Mental disorder is thus the independent (explanatory) variable, and social status is the dependent (outcome) variable.

[question] => Many researchers have viewed socioeconomic status (SES) as a “confounder” of the relationship between race and mental health disorders. Which statement is NOT a part of this idea?
[value] => Array
(
[answer] => 2
[description] => Reason for the Correct Answer:
A confounding variable (confounder) is an extraneous variable that correlates with both the dependent variable and the independent variable.
A perceived relationship between an independent variable (race) and a dependent variable (health) that has been misestimated due to the failure to account for a confounding factor.
Not observing the confounder SES may create a “misleading” (spurious) association between race and health.
