What is a psychological moderator?

A moderator is a variable that affects the strength of the relation between the predictor and criterion variable. Moderators specify when a relation will hold. It can be qualitative (e.g., sex, race, class…) or quantitative (e.g., drug dosage or level of reward).

What is an intervening variable?

intervening variable (mediating variable) A factor mediating the relationship between two other factors (see alsodependent and independent variables). Such a variable is causally situated between them and accounts at least partly for their association.

What is a moderating variable example?

Moderating variables can be qualitative (non-numerical values like race, socioeconomic class or sex) or quantitative (numerical values like weight, reward level or age). For example: Sex is a qualitative variable that moderates the strength of an effect between stress and health status.

What is a dichotomous moderator variable?

If it is, body composition (i.e., the dichotomous moderator variable) moderates the relationship between the amount of exercise performed per week and HDL cholesterol concentration. If it is, gender (i.e., the dichotomous moderator variable) moderates the relationship between the years of education and salary.

How do you identify a moderator variable?

In this equation, if (the interaction between the independent variable and moderator variable) is not statistically significant, then Z is not a moderator variable, it is just an independent variable. If is statistically significant, then Z will be a moderator variable, and thus moderation is supported.

Are considered psychological moderators of stress?

For example, social support, an upbeat personality, meditation and regular physical exercise are examples of stress moderator variables that can help protect someone from the negative effects of a stressful life event such as loss of a job. …

Why do we use moderator variables?

Can moderator be a categorical variable?

Categorical variables are considered to be a good moderator and the effect of categorical variables as a moderator can be measured reliably (Hair et al., 2010, pages 85 through 86). Categorization of continuous variables also makes the analysis and interpretation of results simple.

Researchers generally manipulate some variables (predictor/ dependent variables) in order to measure the impact on one or more other variables (outcome/ independent variables).

How is moderation represented in analysis of variance?

Moderation (statistics) In analysis of variance (ANOVA) terms, a basic moderator effect can be represented as an interaction between a focal independent variable and a factor that specifies the appropriate conditions for its operation.

How is a moderator effect represented in ANOVA?

In analysis of variance (ANOVA) terms, a basic moderator effect can be represented as an interaction between a focal independent variable and a factor that specifies the appropriate conditions for its operation (Baron and Kenny, 1986: p. 1174). Baron, R. M., & Kenny, D. A. (1986).
