Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems interest in an insurance company separate account that invests in the Series II shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing in a portfolio of equity securities, consisting principally of common stocks. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks at the time of investment. The Fund emphasizes a value style of investing seeking well-established, undervalued companies believed by the Fund’s Adviser to possess the potential for capital growth and income. Portfolio securities are typically sold when the assessments of the Adviser of the capital growth and income potential of such securities materially change. The Fund may invest in issuers of small-, medium-, or large sized companies. The Fund may invest up to 25% of its total assets in securities of foreign issuers. The Fund may invest up to 10% of its total assets in real estate investment trusts (REITs). The Fund can utilize derivative instruments, specifically S&P 500 futures, for cash management purposes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through purchasing an offsetting contract, by physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Market risk may affect a single issuer, industry, sector of the economy or the market as a whole. Investments in equity securities generally are affected by changes in the stock markets which fluctuate substantially over time, sometimes suddenly and sharply. The ability of the Fund’s investment holdings to generate income depends on the earnings and the continuing declaration of dividends by the issuers of such securities. The value of a convertible security tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying equity security. Small- and Medium-Sized Companies Risk. During an overall stock market decline, stock prices of small- or medium-sized companies often fluctuate more than stock prices of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger companies and may be less liquid than larger-sized companies. In addition, small- and medium-sized companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies. Value Investing. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than the returns on other styles of investing or the overall stock markets. Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues. Risks of Investing in Real Estate Investment Trusts (REITs). Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and certain other expenses. In addition, REITs depend upon specialized management skills, may be less diversified, may have lower trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Van Kampen Life Investment Trust Comstock Portfolio’s (the predecessor fund) performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark with investment objectives and strategies similar to those of the Fund. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s and the predecessor fund’s past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class II shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Van Kampen Asset Management. The predecessor fund was reorganized into Series II shares of the Fund on June 1, 2010. Series II shares’ returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains. Series I shares are not offered by this prospectus. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).

[1] The Adviser has contractually agreed, through at least April 30, 2013, to waive advisory fees and/or reimburse expenses of Series II shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Series II shares to 0.97% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the number reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; and (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on April 30, 2013.
