Social work develops and uses measures of social and psychological phenomena. These measures are designed to represent concepts or constructs. The constructs most relevant to social work are generally latent variables. In other words, most of the phenomena studied by social work researchers and treated by practitioners are not directly observable. Examples of phenomena not directly observable include self-esteem, depression, stress, closeness, commitment, effectiveness, and many others. These phenomena must be inferred from observations collected on some behavior that is assumed to operationally define the unobservable characteristic of interest. An operational definition is most useful when it delineates boundaries of behavior and distinct points between those boundaries. Typically, measures—scales, indices, and tests—of unique items are developed to measure a particular dimension of social or psychological phenomena. Special considerations must be taken into account for cross-cultural measures. Data are gathered and statistical models are employed to determine the extent to which the scale, or measurement instrument, has functioned as intended. Measures that function as intended are published for use by practitioners.
