The Five Scales Handout
School Use, Neuropsychological Assessment, Confidence in Trauma-informed Assessment,
Appropriate Intervention, and School Confidence.
I used 27 survey items to create five scales. Descriptive statistics were calculated
in order to examine items related to the five scales (school use scale,
neuropsychological assessment use scale, confidence in trauma-informed assessment
scale, appropriate intervention scale, and school confidence scale). Note, all mean
ratings are calculated on the following Likert scale: 1 = Strongly agree, 2 = Agree, 3 =
Neither agree nor disagree, 4 = Disagree, 5 = Strongly disagree.
School use scale. I calculated reliability statistics in order to test the normal
distribution of the school use variables. For the 5-item scale, the Cronbach’s alpha was
.85 (N = 119). It was positive and greater than .70, meaning it provided good support for
internal consistency reliability (Leech et al., 2015). I combined these five items to create
a school use scale for further analysis (Table 4).

Note. Ratings based on a Likert scale: 1 = Strongly agree, 2 = Agree, 3 = Neither agree nor
disagree, 4 = Disagree, 5 = Strongly disagree.

Neuropsychological assessment use scale. I calculated reliability statistics in
order to test the normal distribution of the school use variables. Two statements were
considered with respect to whether neuropsychological assessments were more
accurate and offered better outcomes for IA students. For the 2-item scale, the
Cronbach’s alpha was .78 (n = 44). It was positive and greater than .70; therefore, it
provided good support for internal consistency reliability (Leech et al., 2015). The two
items were combined to create a neuropsychological assessment use scale for further
analysis (Table 3). Originally this scale was meant to have the same five items as the
school use scale, but for neuropsychological assessments. However, Cronbach’s alpha
was low on the neuropsychological assessment use scale. This could have been due to
the relatively small n value of 44. Table 5 displays more information about the other
items related to this scale.

Table 6 displays the agreement level respondents had to selected statement
variables related to the accuracy of assessments. In the section for neuropsychological
assessment, the highest agreement was for “The neuropsychologist provided an
accurate assessment” (M = 2.45). The lowest amount of agreement was for “My child

received a trauma-informed assessment” (M = 3.09). In this table, the n values are low.
The low n in relation to the neuropsychological assessment data could have to do with
the practical fact that such an assessment costs around $5,000, compared to the
school/district assessment, which is free to families, and many families choose not to
have their child assessed that way. This could be because only a total of 70 families
(53%) reported that their children received neuropsychological assessments, and as in
the rest of the survey, many families did not answer all the question.
The second half of Table 6 displays the ratings of accuracy of school/district
assessments. In this table, the n values are higher than in the previous table, and the
standard deviations are higher as well. Highest agreement was for “This assessment
informed my child’s IEP” (M = 2.67). The lowest degree of agreement was for “My child
received a trauma-informed assessment” (M = 4.02).

Confidence in trauma-informed assessments scale. Data in confidence in
trauma-informed assessments variables included five items. For this 5-item scale, the
Cronbach’s alpha was .75 (N = 137). It was positive and greater than .70, thus it
provided adequate support for internal consistency reliability (Leech et al., 2015). The
alpha for this confidence in trauma-informed scale indicated good internal consistancy.
These five items were then combined to create the confidence in trauma-informed
assessments scale that was used for further analysis (Table 7).

disagree, 4 = Disagree to 5 = Strongly disagree.
Appropriate intervention and opportunities scale. I calculated reliability
statistics in order to test the normal distribution of the school use variables. Three
statements were considered with respect to whether trauma-informed assessments
enabled students to receive more appropriate interventions and opportunities. For the 3-

item scale, the Cronbach’s alpha was .81 (n = 92). It was positive and greater than .70;
therefore, it provided good support for internal consistency reliability (Leech et al.,
2015). The three items were combined to create an appropriate intervention and
opportunities scale for further analysis (Table 8).

nor disagree, 4 = Disagree, 5 = Strongly disagree.
School confidence scale. I calculated reliability statistics in order to test the
normal distribution of the school use variables. Twelve statements were considered with
respect to parents’ confidence in the school’s ability to meet the needs of their IA
student. For the 12-item scale, the Cronbach’s alpha was .95 (n = 86). It was positive
and greater than .70; therefore, it provided good support for internal consistency
reliability (Leech et al., 2015). The 12 items were combined to create a school
confidence scale for further analysis (Table 9).

Association Between the Scales
Descriptive statistics were run in order to test the normal distribution of the five
scales. The skewness of the scales is reported in Table 10. From the descriptive
statistics, skew can be examined. “If the skewness is more than +1.0 or less than -1.0
the distribution is markedly skewed” (Leech et al., 2015, p. 22). If this is the case, it
would mean that “one tail of the frequency distribution is longer than the other and if the
mean and median are different, the curve is skewed” (Leech et al., 2015, p. 22). From
the data I can see that most of the variable scales have a skewness between -1.0 and

1.0, but the neuropsychological assessment use scale (see Table 4), shows skewness
for the items “Provided an accurate assessment” to be 1.61 and “Recommendations
matched what I felt my child needed” to be 1.57. These two items are considered
nonnormal distributions. However, Leech et al (2015) state, “there are several ways to
check this assumption in addition to checking the skewness value. If the mean, median
and mode, are approximately equal, then you can assume that the distribution is
approximately normally distributed” (p. 34). In the case of these two items, the means
are 2.45 and 2.56, respectively; the medians are 2.0 for each item and the mode is 2 for
each item. This would meet the criteria laid out by Leech et al. Although these items are
skewed, the t tests and ANOVAs were sufficiently robust so that I was able to proced
with the analysis. That said, it is important to note that there should be some caution
with the interpretations as one of the items was moderately skewed.

Correlations were run for the five scales. Two relationships were statistically
significant. One was the association between the confidence in trauma-informed
assessment scale and the school use scale. The direction of the correlation was
positive. This means school/district assessments were correlated to confidence in

trauma-informed practices. The second was confidence in TI scale versus appropriate
intervention scale. The direction was positive, which means confidence in TI was
correlated to appropriate interventions. These intercorrelations were significant at the p
=.01 level, where N = 81 (school use scale = 0.72, confidence in TI scale = 0.39). (See
Table 11.)
