IQ & the International Cognitive Ability Resource Sample Test

 



Assessment name:  International Cognitive Ability Resource Sample Test (ICAR)

Scale overview: The International Cognitive Ability Resource Sample Test (ICAR-16) is a 16-item assessment of cognitive ability in four domains.

Authors: David Condon and William Revelle

 

Response Type: Items are rated on a scale of agreement from

Scale items

International Cognitive Ability Resource scale items are protected but available to registered users. The 16-items version includes 4-items per cognitive domain. Following are the 4 domains.

LN – Letter number Series

MR – Matrix Reasoning

VR – Verbal Reasoning

R3D – three-dimensional reasoning

Psychometric properties

Merz et al. (2022) reported a normal distribution of International Cognitive Ability Resource scale scores and positive correlations with level of education, income, and a self-estimate of intelligence. There were no gender differences on the total score.

Lace and Evans (2021) found an inverse correlation between spirituality and intelligence using the ASPIRES-SF and the ICARS-16 (r = -0.22 for ASPIRES-SF-R and -0.11 for ASPIRES-SF-S).

Lace and Evans (2021) also reported mean IQ scores using ICAR-16 for religious and nonreligious adults. Those who identified as only religious obtained the lowest intelligence scores. The total ICAR-16 intelligence scores are reported by category identity below. See Table 2 in their article for score details.

Religious = 92.99

Spiritual = 99.37

Religious & Spiritual = 98.86

Not religious or spiritual = 103.73

The effect size comparing Religious and Not religious = .73

 Other data may be found in Condon and Revelle (2014), Revelle et al. (2020), and Dworak et al. (2021).

Autonomy (4 items) 3. Honesty (3 items) 4. Emotional self-concept (5 items)  ðŸ‘‰ [ Read more about Self-Concept and Self-Identity] The PSQ is a Likert-type scale with five response options ranging from totally disagree to totally agree. Reliability and Validity In the first study, coefficient alpha = .85 and in study two, alpha = .83. Data analysis supported a four-dimensional model (see the four categories above). Positive correlations with other self-concept measures were statistically significant. Other notes The authors e...

Authors: Fox, Cashwell, and Picciotto    [ Read more about Spiritual Bypassing in Psychotherapy] Response Type: The 13 items are rated on a four-point scale of agreement. Scale items Data analyses from two ethnically diverse US adult samples supported two factors (Psychological Avoidance, PA; Spiritualizing, SP). PA example: When I am in pain, I believe God will deliver me from it SP example: When someone I know is in trouble, I believe it is because they have done something wrong spiritually.   Psychometric properties Cronbach’salphas: Total scale = .85, PA = .82; Sp = .75. The total SBS score was associated with the ASPIRES subscales except for connectedness. PA was associated with depression and SP with stress and anxiety (DASS-21). The over...
