Methods
Procedure
This study was designed as a quasi-experimental case-control
design. It was approved by the ethics committee for human subi
research of the Faculty of Social Welfare and Health Sciences at Haif-
University. Data was collected between March 2011 and August 2012
The researcher met with cach participant individually in a quiet location
and obtained a signed written informed consent. Each participant
completed a socio-demographic questionnaire followed by an extensive
set of evaluations and questionnaires. Adults with LD were invited to
have the questions read to them out loud, and to receive a free
professional advisory hour in exchange for their participation.
The final sample size of 110 participants (55 adults wíth LD and 55
controls) was determined using a statistical power analysis program [431.
The GPower3 program calculated a critical tof 1.659 with 108 df and a
sample power of 0.831 for 21 central constructs which were examined
with an effect size of 0.5 and a error probability of 0.05.
The inclusion criteria were: 20-50 years of age, mother tongue level
of Hebrew reading and writing, intact vision and hearing or coIrected
with an aid, without motor or neurological disabilities, generally healthy
with no chronic discases or significant injuries that could influence daily
activities and QoL. Participants in the study group were required to
present proof of their LD diagnoses signed by a formal professional. With
respect to the control group, only participants who could answer "no" to
the following two questions were included: "Has anyone ever told you
that you may have a LD?" and "Did you ever think you may have a LD?"
