Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Sternberg's Triangular Theory of Love

Sternberg's Triangular Theory of Love

We typically love the people with whom we form relationships, but the type of love we have for our family, friends, and lovers differs. Robert Sternberg (1986) proposed that there are three components of love: intimacy, passion, and commitment. These three components form a triangle that defines multiple types of love: this is known as Sternberg’s triangular theory of love. Intimacy is the sharing of details and intimate thoughts and emotions. Passion is the physical attraction—the flame in the...

Cattell's 16 Personality Factors

Cattell's 16 Personality Factors

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the fundamental,...

Background:

The Capacity to Love Inventory (CTL-I) is a tool for assessing relationship capacity.
Adapting and validating psychological instruments for specific cultural contexts is crucial for their effective application.

Purpose of the Study:

To examine the reliability and factorial validity of the Capacity to Love Inventory (CTL-I) in a Latvian sample.
To adapt the CTL-I for the Latvian context and assess its psychometric properties.

Main Methods:

A Latvian version of the CTL-I was administered to 649 participants (79% female, 20% male, 1% other).
Reliability was assessed using Cronbach's alpha.
Factorial validity was examined using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA).

Main Results:

The Latvian CTL-I demonstrated adequate to excellent reliability, comparable to the original version after item removal.
A six-factor CFA model and a second-order two-factor EFA/CFA model showed acceptable goodness-of-fit.
Two second-level factors were identified: emotional investment/intimacy and regulation of sexual desire/loss.

Conclusions:

The adapted CTL-I is a psychometrically sound tool for assessing the capacity to engage in and sustain romantic relationships in Latvia.
The findings support the CTL-I's application in personality trait assessment, clinical evaluation, and treatment planning.
Investing in preventive strategies to support relationship capacity and sexual desire regulation is socially beneficial.
