THE SHEPHERD SCALE

Variable:

The Shepherd Scale is designed to assess Christian identity. A unique character­istic of this instrument is that it is based on an explicit biblical operationalization of the Christian faith. The subtitle of the article where the scale is found (Bassett, Sadler, Ko­bischen, Skiff, Merrill, Atwater, & Liver­ more, 1981) is "Separating the Sheep from the Goats." Sheep and goats refer to New Testament (Matt. 25:32) terms used by Jesus to distinguish Christians from non-Chris­ tians. The authors acknowledge that develop­ing such an instrument is fraught with theo­ logical danger and may give the appearance of spiritual arrogance. But the authors also believe that "there is, to some degree, an ob­ servable and measurable life pattern which is distinctively Christian" (p. 342). The au­thors' attempt to measure such a distinctive pattern is thus called the Shepherd Scale.

Description:

The scale consists of 38 items presented in a 4-point ("true" to "not true")· Likert-type format. The items are conceptu­ally divided into two subscales: a 13-item belief subscale and a 25-item Christian walk subscale. The belief subscale measures be­liefs about God in general and about Jesus Christ in particular. The Christian walk sub­ scale measures behaviors, values, and atti­tudes consistent with a Christian lifestyle.

The items were based on the authors' reading of New Testament passages that de­ scribe the qualifications, characteristics, and /or behaviors of a Christian. These passages were grouped according to common themes, and an item was written for each group. The relevant scriptural passages are presented next to each item in the Bassett et al. (1981) article but are not included in this volume and, of course, should not be included in scale administration. An effort was made to write the items in a nonsectarian fashion.

This scale is one of the most frequently cited scales from 1985 to 1994 in the Jour­nal of Psychology and Theology and the Journal of Psychology and Christianity (Jones, Ripley, Kurusu, & Worthington, 1998), two journals that are explicit in their purpose of integrating psychology with claims of the Christian faith.

Practical Considerations:

Administering and scoring of the Shepherd Scale are straightforward. Each item is scored be­ tween one ("not true") and four ("true"), and the overall score is computed by simply summing the scores across all items. Thus scores can range from 38 to 152. No spe­cific cutoff is suggested for separating Christians from non-Christians.

Norms/Standardization: Four studies have reported normative data on the Shepherd Scale:

Reliability:

Bassett et al. (1981) report a test­ retest (at a two-week interval) reliability coef­ficient in their Christian college sample of .82 and found a split-half reliability coefficient of with the same sample. Cronbach's alpha with this sample was .86. A modified Shep­herd Scale (using 29 of the 38 items) by Boivin, Darling, and Darling (1987) had a KR-20 reliability coefficient of .73.

Validity:

Bassett et al. (1981) reported that among their Christian college sample, the Shepherd Scale correlates .41 with Glock and Stark's (1966) Dimensions of Religious Commitment Scale and .64 with King and Hunt's (1975) Ten Dimension Religious Variable instrument. In a second sample with suburban adults, Bassett et al. found that self-identified Christians scored signifi­ cantly higher on the Shepherd Scale than did self-identified non-Christians, t (28) = 6.29, p <.001.

Pecnik and Epperson (1985) found that among state university students, the Shepherd Scale correlated .71 with self-reported impor­tance of religious beliefs, .52 with denomina­tional preference (coded as Christian or non­ Christian; the positive correlation showing that Christians score higher than non-Chris­ tians) , and .43 with self-reported frequency of participation in religious activities.

The Shepherd Scale

Instructions: These questions consider different aspects of Christian experience. Note that some of the items consider how you think about or act toward Christians. These items should not be thought of as exclusive. In other words, having respect for Christians does not mean that you lack respect for non-Christians.
