Not a copyrighted scale

Primary Reference

This scale was developed by Margaret Clark for use in the cold studies (PMBC and PCS3) and has not been otherwise validated.

Purpose

To assess the amount of intimacy participants feel they give to and receive from their partner.

Description

Participants use a 5-point Likert scale to indicate the extent to which they agree or disagree with statements related to their partners.  The scale items comprise 6 subscales that represent the extent to which individuals care about (CI; I care), understand (UI; I understand), and value (VI; I value) their partners, and the extent to which they believe their partners care about (CT; they care), understand (UT; they understand), and value (VT; they value) them.

Scaling

-2 = Disagree, -1 = Slightly Disagree, 0 = Neutral, 1 = Slightly Agree, 2 = Agree

Number of Items

PMBC: 24

PCS3: 12

Variables, Scoring, and Psychometrics

The table below displays the component items for each of the 6 subscales, as well as the internal reliabilities (Cronbach’s α) computed for each of the subscales among married/partnered persons in the PMBC sample (n=55).  Scores for the six subscales are created by summing the values of the component items.  Items appearing in red type were included in both PMBC and PCS3; items appearing in black type were included in PMBC only. 

Table Clark Intimacy Scale

In addition to the 6 subscales, two summary scores were created:  a total respondent intimacy scale (“I Intimacy”), that was comprised of the CI, UI, and VI subscales; and a total partner intimacy scale (“T Intimacy”), that was comprised of the CT, UT, and VT subscales.
