Abstract Results & DiscussionMethods
Purpose
Participants
All participants were residents of CooperRiis Healing
Farm in North Carolina
Demographics
Data Analysis: 5 waves of data
• A two-level Hierarchical Linear Growth Curve
Model (HLM) was used to assess mental health
recovery over time. Five time periods (or waves of
data) were used: admission, 3 months, 6 months,
9 months, and 12 months.
• The strength of a HLM Growth Curve Model over
other regression models is that it can differentiate
between individual starting points (intercepts) as
well as individual change/recovery over time
(slopes) (Raudenbush & Bryk, 2002).
• Both HLM 7 and SPSS 20 (PASW, 2012) were used
for data analysis and the results were comparable
Waves of Data
Procedures
• Grand mean centering
was applied to an
individual’s MHRM-R
scores at each wave
point to simplify the
interpretation of scores
• Maximum Likelihood Estimation (MLE) was used
for all analysisBased on the RCC approach to mental health recovery, the purpose of this
study was to:
(a) Examine the psychometric properties of the Mental Health Recovery
Measure-Revised (MHRM-R) collected from a target population of
individuals with severe and persistent mental health conditions
(b) Assess whether mental health recovery outcomes, based on the MHRM-
R improved over time for the target population
(c) Investigate the roles age, gender, and/or primary diagnosis play in
positive mental health recovery outcomes over time
Target Population: Individuals with Severe and Persistent
Mental Health Conditions
Statistically modeling mental health recovery for individuals with severe
and persistent mental conditions has traditionally been accomplished
using the medical model of recovery which encompasses the elimination
or reduction of symptoms through medication and/or hospitalization. A
more holistic approach gaining support among both clinicians and
consumers is the Recovery-Centered Collaborative Approach to
mental health recovery (the RCC model) which is a person-centered
approach integrating medication with spirituality, hope, physical
wellbeing, life skills, strategies for managing symptoms, and strong
community and family support. Methods: Data from CooperRiis Healing
Farm, a residential treatment facility for individuals with severe and
persistent mental health conditions, specializing in the RCC approach
were examined using a Hierarchical Linear Growth Model (HLGM) to
assess recovery over a twelve month time period. Data included
variables such as age upon admission, gender, and primary diagnosis.
Results: The results from level 1 of the HLGM provided evidence that
there was significant positive growth in recovery scores over time.
Results from level 2 of the HLGM revealed that (1) individuals with
schizophrenia or other psychotic disorders had a significantly higher
recovery score upon admission than individuals with other diagnoses,
suggesting lack of insight into their disorder, (2) females recovered
significantly faster than males, regardless of age or primary diagnosis, (3)
individuals with a diagnosis of personality disorder or substance abuse
recovered ____ than individuals diagnosed with bipolar disorder,
depression, anxiety, attention deficit disorder, or schizophrenia and other
psychotic disorders.

Research Questions
• Interactions: Interactions of independent variables were tested and no
significance was found
• Proportion of Variance Explained: The primary diagnosis of the residents (i.e.,
schizophrenic or not) explains 15.3% of the parameter variance in the initial status
(i.e., where a given resident baseline recovery score will start) and gender
accounts for 10.5% of the parameter variance in growth rates of recovery over
time.
• Final Estimates HLM Growth Model Gender & Primary Diagnosis
Recovery Over Time
Implications for Mental Health Researchers, Clinicians, & Consumers
Implications for Mental Health Researchers, Clinicians, and Consumers
• The MHRM-R is an good measure of mental health recovery and would be appropriate for
researchers and clinicians to utilize in the target population
• This study supports the holistic recovery-centered collaborative approach to recovery as a
viable alternative to the medical model of mental health recovery, even in patients with the
most severe and persistent mental health disorders
• Applied researchers and clinicians can use this information to develop appropriate person-
centered treatments for severe mental health conditions
• Individuals seeking mental health treatment for acute symptoms can have a voice in their
recovery process and maintain hope throughout their journey of symptom management.
Limitations
Recovery is a complex process involving far more than age, gender, and a dichotomized primary
diagnosis, therefore significant limitations are inherent in any explanatory model of recovery over time
• Research Question # 1: Is the MHRM-R a reliable and valid measure of
mental health recovery in the target population?
• Research Question # 2: Does mental health recovery of individuals with
severe and persistent mental health conditions, receiving a recovery-
centered collaborative mental health intervention, improve over time?
o Is there a difference in recovery outcomes over time based on:
• Research Question # 3: gender?
• Research Question # 4: primary diagnosis?
• Research Question # 5: age?
Instrumentation
Mental health recovery was measured using the
Mental Health Recovery Measure-Revised
(MHRM-R: Young & Ensing, 2003). The MHRM-R
is a 30-item self-report survey with a traditional
five-point Likert response scale ranging from 1=
strongly disagree to 5 = strongly agree. Higher
scores indicate more positive recovery outcomes.
Using Confirmatory Factor Analysis and
Cronbach’s alpha to assess the psychometric
properties of the scores on the MHRM-R, it was
concluded that the scores were both valid and
reliable. See Table 2 below.
Psychometric Properties of the Mental
Health Recovery Measure-Revised
Building the Model
• Level 1: The Unconditional Model:
MHRM_CENti = π0i + π1i*(TIME0ti) + eti
• Level 2: The Conditional Model:
π0i = β00 + β01*(AGEi) + β02*(GENDERi)
+ β03*(DIAGNOSIi) + r0i
π1i = β10 + β11*(AGEi) + β12*(GENDERi) +
β13*(DIAGNOSIi) + r1i
All statistical tests were conducted with α =.05.
• Research Question # 1: The scores from the target population had excellent internal consistency
and good model fit.
• Research Question # 2: Evidence supported growth (recovery) over time
Level 1: Unconditional Model:
This model only included the MHRM-R recovery scores as the outcome variable and TIME as an
independent variable. The unconditional model determined that there was indeed growth over time,
allowing the addition of Level 2 to the model, where possible explanatory variables were included
(Raudenbush & Bryk, 2002).
Mean Intercept: Estimations of the mean intercept, 𝛽00= -0.804, p = 0.482, were not significant
indicating that this parameter did not describe the average admission recovery score.
Mean Growth Trajectory: The mean growth rate, 𝛽10=1.06, p = 0.025, for the MHRM-R recovery
scores was significant, providing evidence that residents were gaining an average of 1.06 points
every three months to their MHRM-R recovery scores
Mean Growth Trajectories Individual Growth Trajectories
Results & Discussion
(1)
Level 2: Conditional Model: See Table 5
Findings from the unconditional model confirmed the requisite of a conditional
model with explanatory variables of personal characteristics (i.e., age, gender, and
primary diagnosis) added to the model, at Level 2:
• Research Question # 3: There was a significant difference in the growth
trajectory of recovery outcomes based on gender ( 𝐵11 = −1.13, 𝑝 = 0.02).
Gender was a significant explanatory variable for growth over time, providing
evidence that, regardless of diagnosis or recovery score upon admission, females
recovered faster than males.
• Research Question # 4: Baseline Scores: Scores on the MHRM-R differed
significantly based on primary diagnosis, ( 𝐵02 = 2.39, 𝑝 = .046) with individuals
presenting with schizophrenia scoring higher upon admission than those with
other diagnoses, suggesting lack of insight into their disorder (Young, 2003)
• Research Question # 5: :There was not a significant difference in recovery
outcomes based on the residents’ age for the intercept (i.e., where the residents’
started; p = 0.434, nor in their growth trajectories (i.e., the residents’ recovery over
time; p = 0..141)
Implications & Limitations
(2)
(3)
 Females showed significant recovery over time
regardless of diagnosis or scores upon admission
 Scores upon admission differed significantly based
on primary diagnosis
[a] [b] [c] [d] [e]
Some individuals
completed the MHRM-R
up to one month
following admission
and, therefore,
experienced the benefits
of treatment prior to
their first assessment
The MHRM-R is a self-
report measure, and
while the results show
significant growth in
recovery scores, they
are only based on the
treatment received at
CooperRiis
The growth model was
based on 12 months of
data. If additional data
had been available,
trajectories may or may
not have improved for
both males and females
Small effect size: Only
10.5% of the variance of
growth rates based on
gender was explained by
the model, suggesting
the need for additional
explanatory variables in
the model
Collapsing primary diagnosis
into only two categories may
have reduced the amount of
variance explained by the
model, severely limiting the
ability to detect true variance in
a multitude of diagnoses and
comorbidities

Psychometric Properties of the Mental Health Recovery Measure-Revised Building the Model • Level 1: The Unconditional Model: MHRM_CENti = π0i + π1i*(TIME0ti) + eti • Level 2: The Conditional Model: π0i = β00 + β01*(AGEi) + β02*(GENDERi) + β03*(DIAGNOSIi) + r0i π1i = β10 + β11*(AGEi) + β12*(GENDERi) + β13*(DIAGNOSIi) + r1i All statistical tests were conducted with α =.05. • Research Question # 1: The scores from the target population had excellent internal consistency and good model fit. • Research Question # 2: Evidence supported growth (recovery) over time Level 1: Unconditional Model: This model only included the MHRM-R recovery scores as the outcome variable and TIME as an independent variable. The unconditional model determined that there was indeed growth over time, allowing the addition of Level 2 to the model, where possible explanatory variables were included (Raudenbush & Bryk, 2002). Mean Intercept: Estimations of the mean intercept, 𝛽00= -0.804, p = 0.482, were not significant indicating that this parameter did not describe the average admission recovery score. Mean Growth Trajectory: The mean growth rate, 𝛽10=1.06, p = 0.025, for the MHRM-R recovery scores was significant, providing evidence that residents were gaining an average of 1.06 points every three months to their MHRM-R recovery scores Mean Growth Trajectories Individual Growth Trajectories Results & Discussion (1) Level 2: Conditional Model: See Table 5 Findings from the unconditional model confirmed the requisite of a conditional model with explanatory variables of personal characteristics (i.e., age, gender, and primary diagnosis) added to the model, at Level 2: • Research Question # 3: There was a significant difference in the growth trajectory of recovery outcomes based on gender ( 𝐵11 = −1.13, 𝑝 = 0.02). Gender was a significant explanatory variable for growth over time, providing evidence that, regardless of diagnosis or recovery score upon admission, females recovered faster than males. • Research Question # 4: Baseline Scores: Scores on the MHRM-R differed significantly based on primary diagnosis, ( 𝐵02 = 2.39, 𝑝 = .046) with individuals presenting with schizophrenia scoring higher upon admission than those with other diagnoses, suggesting lack of insight into their disorder (Young, 2003) • Research Question # 5: :There was not a significant difference in recovery outcomes based on the residents’ age for the intercept (i.e., where the residents’ started; p = 0.434, nor in their growth trajectories (i.e., the residents’ recovery over time; p = 0..141) Implications & Limitations (2) (3)  Females showed significant recovery over time regardless of diagnosis or scores upon admission  Scores upon admission differed significantly based on primary diagnosis [a] [b] [c] [d] [e] Some individuals completed the MHRM-R up to one month following admission and, therefore, experienced the benefits of treatment prior to their first assessment The MHRM-R is a self- report measure, and while the results show significant growth in recovery scores, they are only based on the treatment received at CooperRiis The growth model was based on 12 months of data. If additional data had been available, trajectories may or may not have improved for both males and females Small effect size: Only 10.5% of the variance of growth rates based on gender was explained by the model, suggesting the need for additional explanatory variables in the model Collapsing primary diagnosis into only two categories may have reduced the amount of variance explained by the model, severely limiting the ability to detect true variance in a multitude of diagnoses and comorbidities Table 2 Model Fit Indices MHRM-R (30 items) Acceptable Fit Satorra-Bentler Scaled χ2 708.50, p < .0001 p value > .05 Non-Normed Fit Index (NNFI) 0.95 ≥ .95 Comparative Fit Index (CFI) 0.96 ≥ .95 Standardized RMR (SRMR) .063* ≤ .08 Root Mean Square Error of Approximation (RMSEA) 0.084 < .06 to .08 Cronbachs α 0.941 > .80 Evidence of Validity and Reliability: Fit Indices and Cronbach's alpha for the MHRM-R * According to Hu and Bentler (1999), when data is non-normal or n is small, SRMR is preferred over RMSEA Table 1 Years N Gender Primary Diagnosis 2003-2012 277 Female Schizophrenia 27 Range 18-71 Other Diagnoses 85 Mean 31.71 Male Schizophrenia 77 SD 10.61 Other Diagnoses 88 Participants Descriptive Statistics 122 155 Age (in years)n
