Brainard Occupational Preference Inventory
By:KRISTINE JOY B. GARCIA
Description of the TEST
The Brainard Occupational Preference Inventory
permits a systematic study of a person’s interests.
It is a standardized questionnaire designed to bring to the fore the facts
about a person with respect to his occupational interests.
The purpose is to help to intelligently and objectively discuss his occupational and
educational plans.
The Inventory can be administered in about 30 minutes. It is intended for
students in grades 8-12 and adults.
CautionREQUIRES a relatively low level of
reading skill. HENCE, it may appropriately be used at lower educational levels than similar
instruments which contain more difficult reading material.
Adults with limited educational backgrounds may also be able to react with greater understanding to the item of the Inventory.
Components
The Brainard Occupational Preference Inventory yield scores in six broad occupational
fields for each sex.
Both boys and girls obtain scores in the fields identified as Commercial, Mechanical, Professional, Esthetic, and Scientific.
Only boys answer the item which yield an Agricultural score;
Only girls answer then items for a personal
service score.
continuation
Each field contains twenty questions divided equally
among four occupational
sections.
The subject responds to each item by indicating
whether he strongly dislikes the activity,
dislikes it, is neutral about it, likes it, or strongly likes
it, or strongly likes it.
Answers are marked on a separate answer sheet by drawing a line which indicates the choice of
response.
History
In 1932 the Specific Interest
Inventory by Paul P. Brainard was published in four forms. The forms were M
and W, for men and women; B and G, for boys
and girls.
The four inventories had been carried on since 192. (Refer to
Fryer’s The Measureme
nt of Interests,
Henry Holt and
Company, 1931).
All four forms of the
Specific Interests Inventory
were widely used.
REVISIONS
Classification of the 140 question into 28 Sections and these, in turn,
into 7 Occupational Fields.
Wording of items were made applicable to both sexes and for high
school through adult ages.
Grouping of items which conformed in general to the code plan of the
Dictionary of Occupational Titles, and also to the large fields of interest
(proposed by Dr. Alfred Lewerenz of the Educational Research and
Guidance Section of the Los Angeles City Schools).
In 1955, Form A was reviewed and changes in wording were made in a
few items.
Continuation…Agricultural score for girls and the Personal Service score for boys were removed since each of these fields was apparently more meaningful for one sex
than the other.
Inventory items were put into a new
booklet and the answer sheet was
redesigned.
Scoring system was changed to
eliminate negative scores on items.
The answer sheet can now be scored either by hand or
by machine.
FIELDSField
• I – Commercial • II – Mechanical • III – Professional • IV – Esthetic • V – Scientific • VI – Agricultural (for
Boys)• Personal Service (or
girls)
Item numbers
• 1-20• 21-30; 41-50• 31-40; 51-60• 61-70; 81-90• 71-80; 91-100• 101-120
ReliabilityThe first reliability test was a TEST-RETEST study in 1955 to the entire
tenth grade in an academic high school in Yonkers, NY.
The time interval between tests was one week. The test-retest reliability coefficients of the six field scores are for each sex.
2nd reliability study in which scores on odd and even items were correlated was based on 683 boys and 200 girls in grade 12.
The odd-even correlation coefficients are corrected by the Spearman-Brown formula.
Both studies indicate that the reliabilities of the field scores are adequately high for most purposes to which these scores will be put.
No data have been gathered to establish the effectiveness of the Inventory scores as predictors of success in specific occupations.
ValidityThe scores from the BOPI
show very little relationship to the scores derived from
the Kuder Personal Preference Record.
BOPI gains different data from the Kuder PPR.
The Kuder items measure interests by forcing the
subjects to choose among three activities indicative of different types of interests.
While BOPI permits the student to indicate his
strength of interest in other activities without forcing
him to subordinate interest in other activities.
Scoring
The weights for the various responses are: 1 for SD; 2 for D; 3 for N; 4 for L; and 5 for SL.
Score each field by summing the appropriate
weights for the given responses .
Record the scores in the
proper boxes at the top edge of
the answer sheet.
The lowest possible score for any fields is 20, meaning that the subject has marked
the SD for each item;
the maximum score is 100, in which case every item has been marked
through the SL.
Omitted Items• If only one item in a field has
been omitted, treat it as a response of N (Neutral) and
give it a weight of 3. But when two or more items in a field have not been mark, no score should be obtained for that particular field as such as score could only be an
approximation of the subject’s interest.
