Semantic differentials and the process of developing one to measure maternal role competence

Area of Science:

• Nursing Research
• Psychometrics
• Social Sciences

Background:

• The semantic differential (SD) technique is increasingly utilized by nurse investigators.
• Understanding SD methodology is crucial for appraising findings derived from SD data.
• The technique involves respondents rating concepts on bipolar adjective scales.

Purpose of the Study:

• To elucidate the semantic differential (SD) technique for nurse investigators.
• To demonstrate the application of SD in measuring maternal role competence.
• To explore the dimensional structure of SD when applied to novel concepts.

Main Methods:

• Description of the semantic differential (SD) technique, including construction and scoring.
• Application of SD to measure the concept of "myself as a mother."
• Factor analysis to examine the dimensional structure of the developed SD instrument.

Main Results:

• The study explains the construction and multidimensional nature (evaluative, potency, activity) of the SD technique.
• Factor analysis of an SD for "myself as a mother" indicated that adjective pairs did not align with typical SD dimensions.
• Alternative dimensions emerged and were supported by correlations with other maternal role measures.

Conclusions:

• The semantic differential (SD) technique is adaptable for clinical populations due to its ease of use.
• The development of an SD for maternal role competence revealed unique dimensional structures.
• The SD technique shows promise for measuring complex constructs like maternal role competence.
