Perception of Legal Pressure Scale Scoring Notes The PLP instrument is a work in progress that remains under development. The current version includes 35 items. Item scores are summated to yield an overall score with higher scores indicating greater perceived legal pressure. At present, all items in the instrument are utilized for scoring except for questions 6 through 9. The tool is structurally divided into 3 subsections. The first 5 items provide information about the criminal justice and treatment actors that referred and are monitoring the respondent, and the nature of promises made by the respondent regarding the treatment mandate. The second section consists of Likert-scaled items about different aspects of coerced treatment. The last section addresses specific expectations and perceptions about consequences for failing to carry out the treatment mandate.
Questions 1 thru 5 are scored as counts of the actors identified by the respondent. To make this scoring comparable with the rest of the items and to reduce skewed scores, each of these is truncated at 3 (i.e., 3 or more on an item is scored as ‘3’). Scores can thus range from 0 to 3.
The Likert-type items in questions 10-31 are scored as 0-3. Responses on the form are recorded as 1-4, so 1 must be subtracted from the entered values, leaving values ranging from 0-3. The following items must be reverse coded so higher scores reflect greater perceived coercion: 11, 13, 14, 15, 16, 19, 20, 22, 23, 26, 27, 28, 30.
The final 4 items, questions 32-35, utilize a severity scale that ranges in value from 1 to 7. Scores associated with responses A-J (each of which specify a legal or treatment consequence) are shown below. For these items to be standardized, each scored value is divided by 2.33. Each of the items can thus range from 0-3.
2 years in prison (F)
1 year in prison (B)
1 year in jail (H)
6 months in jail (C)

The 31 scored items are summed and then rounded to the nearest integer (to eliminate decimals from items 32-35) to create the total PLP score. The hypothesized subscale dimensions of the PLP, including knowledge, monitoring, enforcement, and severity, are shown on the next page.
