Love Scale: A Review of Measurement and Construct Validity
Abstract
The purpose of this review is to analyze the measurement and construct validity of the Love Scale, a popular self-report measure of intimate relationships. This review examines the literature on the Love Scale and considers the available evidence for the instrument’s psychometric properties. The research suggests that the Love Scale is a reliable and valid measure of romantic relationships, with good internal consistency and test-retest reliability. However, the literature also suggests that the Love Scale may suffer from some limitations, such as lack of discriminant validity and questionable construct validity. Overall, the evidence supports the use of the Love Scale as a valid measure of intimate relationships.

Introduction
Intimate relationships are an important part of life for many people. Thus, it is important to have valid and reliable measures of these relationships. The Love Scale is a popular self-report measure of intimate relationships, developed by Hatfield and Sprecher (1986). The Love Scale consists of 30 items that assess various aspects of romantic relationships, such as commitment, trust, and intimacy. The purpose of this review is to analyze the measurement and construct validity of the Love Scale.
Measurement Validity
The Love Scale has been found to have good internal consistency, with Cronbach’s alpha values ranging from .86 to .92 (Hatfield & Sprecher, 1986; Le & Agnew, 2003). Test-retest reliability has also been demonstrated, with a correlation of .77 over a 3-month period (Hatfield & Sprecher, 1986).
Construct Validity
The construct validity of the Love Scale has been tested in several studies. Hatfield and Sprecher (1986) found that the Love Scale correlated positively with other measures of love and commitment, such as the Passionate Love Scale and the Commitment Scale. This suggests that the Love Scale is a valid measure of romantic relationships. However, Le and Agnew (2003) found that the Love Scale did not correlate significantly with other measures of relationship satisfaction, such as the Marital Satisfaction Inventory. This suggests that the Love Scale may lack discriminant validity.
Conclusion
Overall, the evidence suggests that the Love Scale is a reliable and valid measure of romantic relationships. The instrument has good internal consistency and test-retest reliability, as well as positive correlations with other measures of love and commitment. However, the Love Scale may suffer from some limitations, such as lack of discriminant validity and questionable construct validity.
