Construct Validity of the WISC-IV With a Referred Sample: Direct Versus Indirect Hierarchical Structures.
Canivez, Gary L.
School Psychology Quarterly, Jul 29 , 2013

The Wechsler Intelligence Scale for Children–Fourth Edition (WISC-IV) is one of the most frequently used intelligence tests in clinical assessments of children with learning difficulties. Construct validity studies of the WISC-IV have generally supported the higher order structure with four correlated first-order factors and one higher-order general intelligence factor, but recent studies have supported an alternate model in which general intelligence is conceptualized as a breadth factor rather than a superordinate factor (M. W. Watkins, 2010, Structure of the Wechsler Intelligence Scale for Children–Fourth Edition among a national sample of referred students, Psychological Assessment, Vol. 22, pp. 782–787; M. W. Watkins, G. L. Canivez, T. James, K. & R. Good, in press, Construct validity of the WISC-IVUK with a large referred Irish sample, International Journal of School and Educational Psychology). WISC-IV core subtest data obtained from evaluations to assess learning difficulties in 345 children (224 boys, 121 girls) were examined. One through four, first order factor models and indirect versus direct hierarchical models were compared using confirmatory factor analyses. The correlated four-factor Wechsler model provided good fit to these data, but the direct hierarchical model showed statistically significant improvement over the indirect hierarchical model and correlated four-factor model. The direct hierarchical model was judged the best explanation of the WISC-IV factor structure, with the general factor accounting for 71.6% of the common variance while the first order factors accounted for 2.4–10.3% of the common variance. Thus, the results with the present sample of referred children were similar to those from other investigations (G. E. Gignac, 2005, Revisiting the factor structure of the WAIS-R: Insights through nested factor modeling, Assessment, Vol. 12, pp. 320–329; G. E. Gignac, 2006, The WAIS-III as a nested factors model: A useful alternative to the more conventional oblique and higher-order models, Journal of Individual Differences, Vol. 27, pp. 73–86; P. Golay, I. Reverte, J. Rossier, N. Favez, & T. Lecerf, 2012, Further insights on the French WISC-IV factor structure through Bayesian structural equation modeling.

Watkins, 2010, Structure of the Wechsler Intelligence Scale for Children–Fourth Edition among a national sample of referred students, Psychological Assessment, Vol. 22, pp. 782–787; M. W. Watkins, G. L. Canivez, T. James, K. & R. Good, in press, Construct validity of the WISC-IVUK with a large referred Irish sample, International Journal of School and Educational Psychology) supporting primary interpretation of the Full Scale IQ rather than the factor index scores.

Incremental criterion validity of WAIS–IV factor index scores: Relationships with WIAT–II and WIAT–III subtest and composite scores.
Canivez, Gary L.
Psychological Assessment, Vol 25(2), Jun 2013

The present study examined the incremental validity of Wechsler Adult Intelligence Scale–4th Edition (WAIS–IV; Wechsler, 2008a) factor index scores in predicting academic achievement on the Wechsler Individual Achievement Test–2nd Edition (WIAT–II; Psychological Corporation, 2002a) and on the Wechsler Individual Achievement Test–3rd Edition (WIAT–III; Wechsler, 2009a) beyond that predicted by the WAIS–IV Full Scale IQ (FSIQ). As with previous intelligence test incremental validity studies, the WAIS–IV FSIQ accounted for statistically significant and generally large portions of WIAT–II and WIAT–III subtest and composite score variance. WAIS–IV factor index scores combined to provide statistically significant increments in variance accounted for in most WIAT–II and WIAT–III subtest and composite scores over and above the FSIQ score; however, the effect sizes ranged from trivial to medium as observed in investigations with other intelligence tests (i.e., Glutting, Watkins, Konold, & McDermott, 2006; Youngstrom, Kogos, & Glutting, 1999). Individually, the WAIS–IV factor index scores provided trivial to small unique contributions to predicting WIAT–II and WIAT–III scores. This finding indicated that the FSIQ should retain primacy and greatest interpretive weight in WAIS–IV interpretation, as previously indicated by WAIS–IV subtest variance partitions form hierarchical exploratory factor analyses (Canivez & Watkins, 2010a, 2012b).

It seems publishing academic psychologists aren't as smart as political forum poster "Iolo". Or did I get that the wrong way around?

 

What pays pays, kid. How do you know I'm not an academic psychologist anyway?

 

Higher group IQ results in higher income, greater educational attainment and less anti-social behavior. Whatever you want to claim, the previous is certainly better for society; therefore, groups w/ higher IQ are more desirable.

 

There's no cultural component to Raven's Progressive matrices or Backward Digit Span tests.

Asians outperform Whites and Whites outperform Blacks on these tests.

Btw, there is, as I said, cross-cultural agreement on IQ regarding adopted Koreans in the Netherlands, Belgium and the United States.

IQ tests have weathered decades of criticism, and some of her skeptics have become her proponents.

 

How did they match up with the family raising them? Seems someone left that fact out...

 

1 Hong Kong 107
2 South Korea 106
3 Japan 105
4 Taiwan 104
5 Singapore 103

South Korea's average IQ is 106, which is just one point higher than that of Japan, and the IQ differences between Asian countries may be nothing more than statistical errors. It's also wrong to presume that Asians are intellectually superior to whites and adults in Germany and the Netherlands have the highest average IQ at 107, which is one point higher than that of South Korea. There are also IQ differences between European countries and northern Europeans generally score better than southern Europeans: Poland (106), Sweden (104), Italy (102), Austria (101), Switzerland (101), the UK (100), Belgium (99), Spain (98 ), Hungary (98 ), Russia (96), Greece (95), France (94), Romania (94), Turkey (90) and Serbia (89).

 

iq tests are culturally sensitive, something I learned in a Uni Psychology 101 class 40 years ago and here you are claiming someone else is ignorant, eeew the irony...

 

and china scores at 100 which is considerably lower than the ethnic chinese populations of Hong Kong, Taiwan and Singapore...this is an impossibility according the those with a racist agenda, obviously it's not race that's involved but environment, advanced and intense education in Hong Kong, Taiwan and Singapore as well as a considerably higher average standard of living than found in mainland China...

 

I don't know how anyone could reasonably believe Korean children in three separate adoption programs were disproportionately matched w/ high IQ families.

Anyway, you can read the studies or about the studies:

Except for the conveniently ignored statement from the OP acknowledging environment also plays a factor.

 

yeah I already pointed out that adoptive families are generally better educated and wealthier than average, the adopted kids are benefiting from an enriched environment, better health, nutrition, educational opportunities etc, optimum conditions for intellectual development...

 

Guess you'll care to discuss control groups and average IQ's for adopted White children?

 

...you asserted that it's racial , now you want to backtrack because your "racial" assertions without basis...com'on tell us why China scores no better than europe? a 1/5 of humanity the vast majority of the "asian race" scores less than inferior northern euro countries...

 

What an amazing coincidence. Koreans get adopted by high status families, Whites by average status families, and Blacks by low status families. Every time.

Cool argument bro.

- - - Updated - - -

There is within race genetic variation.

 

I asserted a racial component and acknowledged heritability accounting for around 80% of IQ.

You should go back to the OP and dispute any assertion I make.

Chinese and Koreans raised in the West have higher IQ and general intelligence than Whites.

That matters far more than how Chinese are doing in a developing nation.

 

You are spouting a whole lot of convoluted non-sense. IQ tests enable us to identify individual who possess greater general abilities in gross pattern recognition. Much like bench press, squat, 40 yard sprint times, shuttle times constitute a composite view of the raw potential of an athlete, intelligence tests seek and SUCCEED at predicting raw academic talent.

While possessing the raw talent may be indicative success, it is not a guarantee. It is sound science.

 

adopting a kid from S korea will end up costing the adoptive parents $30 to 35,000 instantly the wealth/education of the parents becomes a factor

 

there's a stroke of brilliance, Hong Konger's, Taiwanese and Singaporeans are now "separate races" the intellectual lunacy grows...

 

I think the question we need to ask is how well IQ tests intelligence in the real world. In other words, what do IQ tests actually measure, and furthermore does what we measure have anything to do with baseline intelligence. I remember taking those tests, and they were all pen and paper tests of word recognition (analogies and so on) or picking the next pattern in a sequence. I think it matters because those things are not necessarily tests of smarts, just of recognizing patterns. At that point, suduko is as valid as any intelligence test -- but it's not even a test, it's a puzzle. Could your high scoring Asians figure out other kinds of tests?

 

Its about 70-80% hereditary and 20-30% environment. It would make sense that hongkong and Taiwan score higher than China given the 20-30% veriability due to environment.

 

and how would compare a highly literate population with a population with zero literacy? obviously it's impossible...even the attitude various social/ethnic groups would have toward a test is a factor, one societies may work diligently to give the correct answer another may have a lackadaisical bemused attitude toward the test...tests really only have relevancy within a single culturally similar group...and even within that uniform group test results only indicate there is a difference not that any one individual is definitively smarter than another, iq can change throughout a individuals life span...

 

The tests were developed by a certain race (Caucasian), and are likely somewhat accurate for them. Had these tests been developed by Asians, they would likely be accurate for that culture...though less so for other races and cultures.

 

hypothetically we are all born with a similar base so heredity does play an obvious part...but environment is the most important component because environment can be manipulated and along with it IQ...

music proficiency has ability to effect the brain and intelligence, children who study music score higher on IQ tests...music students perform on average better at Spatial-temporal skills -Math ability-Reading skills-Vocabulary-Verbal memory-Phonemic awareness ...one source I can upon estimated music study could raise IQ by as much as 7 points...so a society that emphasizes music could attain an average higher IQ scores vs a society that has minimal musical culture... do we infer the musical culture is smarter than the other?

so if we hypothetically assume we all start out with an IQ of 70-80 the 10 point difference being the luck of heredity, there is 20-30 points left to environmental influences, so then we're looking at a final iq range of 90-110(heredity+environment=score)...
