HOPE - How to measure hope








The Adult Hope Scale developed by C. R. Snyder of the University of Kansas is an easy to use measure of hope. The original scale has 12-items, which measure two dimensions of hope based on hope theory. Four measure agency and four measure pathways--the other four are distractors.


The agency concept measures the capacity to focus energy on a goal. The pathways concept assesses plans to achieve goals. In recent studies, the four distraction items are often dropped leaving 8-items. Researchers often use the total score for the 8-items as a measure of trait (aka dispositional) hope.





I have also included a Spanish language measure of hope in this post.

Here's the text we (Sutton et al., 2018) used to refer to the scale along with our findings.


The items used a response format of 1 = definitely false to 8 = definitely true. A sample item is, “I meet the goals I set for myself.” Snyder et al. (1991) reported alphas between .79 and .95 in four samples. 
In our two studies, the alpha reliability values were .82 and  .95.

As you might expect, hope is positively correlated with well-being, which provides some evidence supporting validity. Hope was significantly correlated with the Schwartz Outcome Scale in both studies (.64, .76) and with the Theistic Spiritual Outcome Scale in study 2 (.72).

Using the Hope Scale

Counselors and psychotherapists may consider the scale in assessment of clients because it strongly predicts satisfaction with therapy and patient well-being, which are used as outcome measures as noted above (See Sutton et al., 2018)

Researchers may want to use hope in a variety of surveys looking at characteristics of populations. The reliability values of the items vary with the study yet indicate an overall consistency in many contexts.

La Esperanza

A Spanish hope scale (Escala de Esperanza) is also available. An article suggests adequate psychometric properties for a 28-item version (Uribe, Bardales, & Herth, 2012).

Measuring Spiritual Outcomes in Psychotherapy














The Theistic Spirituality Outcome Scale (TSOS) has potential as a useful outcome measure.


Recently, a group of us completed a study of clients who saw Christian counselors. We assessed their current well-being using two measures: The Schwartz Outcome Scale (SOS) and the Theistic Outcome Scale (TSOS). (See references below.)


The TSOS was designed by Richards (2005) as a measure of well-being for people associated with a theistic religion like Christianity, Judaism or Islam. We used the 17-item version, which uses a 5-point response format from 1 = never to 5 = almost always to rate each item (e.g., “I felt spiritually alive.”).


Reliability

We only calculated coefficient alpha, which was strong at .95.

Validity

The TSOS was significantly correlated with ratings of satisfaction with Christian counseling (.65) and likelihood of returning to Christian counseling (.62).

It was significantly correlated with the SOS measure of general well-being (.84).

Other significant correlations were:

TIPI (a Big 5 measure; Gosling et al., 2003)


Extraversion .34
Agreeableness .50
Neuroticism .51
Conscientiousness .39
Snyder's Hope Scale .72 (Snyder et al., 2010)

Attachment to God Inventory (Beck & McDonald, 2004)
  Avoidant  -.55
  Anxious   -.40

Religious Practices Index  .41 (See Sutton et al., 2016)

Intratextual Fundamentalism Scale .56 (See Williamson et al., 2010)
