D. Data Analysis
Vanderstoep and Johnston 2009: 199 mention that there are five research methods in  analyzing  data,  i.e.  ethnography,  phenomenology,  case  study,  textual  analysis,  and
applied  research.  This  research  employed  textual  analysis,  which  involved  the identification and interpretation of a set of verbal and behavioral communication of the
main  character  as  a  schizophrenic  in  The  Uninvited  movie.  Generally,  this  research employed some steps of data analysis as follows.
1. Firstly,  the  themes  that emerged  from  the  raw  data  were  identified,  and then  they
were  categorized  into  either  types  of  hallucination,  delusion,  or  formal  thought disorder.
2. Then, each categorization was classified by using a data sheet.
3. After  that,  each  datum  which  had  been  classified  in  the  data  sheet  was  analyzed
based on the research questions. 4.
Then, each datum was interpreted based on its context to answer the three research questions.
5. Then, the research findings were reported through textual description.
6. Finally, some conclusions were drawn.
E. Trustworthiness
To  establish  the  validity  truthfulness  and  reliability  consistency  of  the  data, research  will  employ  triangulation  Vanderstoep  and  Johnston,  2009:  179.  According
to  Hussein  2009:  3,  triangulation  is  a  kind  of  validity  procedure  where  a  researcher uses  the  combination  of  two  or  more  methodological  approaches,  theoretical
perspectives,  data  sources,  investigators,  or  analysis  methods  to  study  the  same phenomenon.  Therefore,  there  are  five  types  of  triangulation,  i.e.  methodological
triangulation,  theoretical  triangulation, data  triangulation  also  referred  to  data  sources triangulation, investigator triangulation, and analysis triangulation.
To  enhance  the  trustworthiness  of  the  data,  this  research  employed  theoretical triangulation  by  referring  to  schizophrenia  theories  from  various  books  and  journals,
especially  those  containing  information  about  hallucination,  delusion,  and  formal thought  disorder.  Moreover,  the  findings  of  the  research  were  triangulated  by  the
researcher’s two fellow university students majoring in linguistics.
